Expert subject Technology date March 2010 In telecommunications , the term cyclic prefix refers to the prefixing of a symbol data symbol with a repetition of the end. Although the receiver is typically configured to discard the cyclic prefix samples, the cyclic prefix serves two purposes. As a guard interval , it eliminates the intersymbol interference from the previous symbol. As a repetition of the end of the symbol, it allows the linear convolution of a frequency selective multipath channel to be modelled as circular convolution, which in turn may be transformed to the frequency domain using a discrete Fourier transform . This approach allows for simple frequency domain processing, such as channel estimation and equalization. In order for the cyclic prefix to be effective i.e. to serve its aforementioned objectives , the length of the cyclic prefix must be at least equal to the length of the multipath channel. Although the concept of cyclic prefix has been traditionally associated with OFDM systems, the cyclic prefix is now also used in single carrier systems to improve the robustness to multipath. Principle Cyclic prefix is often used in conjunction with modulation in order to retain sinusoid sinusoids properties in multipath propagation multipath channels. It is well known that sinusoidal signals are eigenfunctions of linear , and time invariant systems. Therefore, if the channel is assumed to be linear and time invariant , then a sinusoid of infinite duration would be an eigenfunction ... this property in the part of the symbol after the cyclic prefix.

In mathematics , more specifically in ring theory , a cyclic module is a module mathematics module over a ring which is generated by one element. The term is by analogy with cyclic group s, that is groups which are generated by one element. Definition A left R module M is called cyclic if M can be generated by a single element i.e. M x R x rx r &isin R for some x in M . Similarly, a right R module N is cyclic, if N y R for some y &isin N . Examples Every cyclic group is a cyclic Z module. Every simple module simple R module M is a cyclic module since the submodule generated by any nonzero element x of M is necessarily the whole module M . If the ring R is considered as a left module over itself, then its cyclic submodules are exactly its left principal ideal s as a ring. The same holds for R as a right R module, mutatis mutandis . If R is F x , the ring of polynomials over a field F , and V is an R module which is also a finite dimensional vector space over F, then the Jordan block s of x acting on V are cyclic submodules. The Jordan blocks are all isomorphic to F x x &lambda sup n sup there may also be other cyclic submodules with different annihilators see below. Properties Given a cyclic R module M which is generated by x then there exists a canonical isomorphism between M and R Ann sub R sub x , where Ann sub R sub x denotes the Annihilator ring theory annihilator of x in R .

Unreferenced date December 2009 A Cyclic pump is an Equipment apparatus which moves a fluid in a periodic uni directional direction from one containment system to another while overcoming static conditions that would, without intervention, not move. The intervention predicated by the pump alters pressures, volumes and sometimes temperatures of fluids gasseous, liquid, colloidal, plasmic, etc. in such a way that the fluids are transported to other chambers or enclosures including pipes , thus flowing in a consistent direction, usually having characteristics of pulsation as is the case with the Human heart or of uniform motion as is the case with an Automobile motor oil pump .

Cyclic stress in engineering refers to an internal distribution of forces a stress that changes over time in a repetitive fashion. As an example, consider one of the large wheels used to drive an aerial lift such as a ski lift . The Wire rope wire cable wrapped around the wheel exerts a downward force on the wheel and the drive shaft supporting the wheel. Although the shaft, wheel, and cable move the force remains nearly vertical relative to the ground. Thus a point on the surface of the drive shaft will undergo tension when it is pointing towards the ground and compression when it is pointing to the sky. Because the wheel rotates many times during the use of the machine, this cycle of Tensile stress tension and Compressive stress compression is repeated many times &mdash hence the name cyclic stress. Types of cyclic stress Cyclic stress is frequently encountered in rotating machinery where a bending moment is applied to a rotating part. This is called a cyclic bending stress and the aerial lift above is a good example. However, cyclic axial stress es and cyclic torsional stress es also exist. An example of cyclic axial stress would be a bungee cord see bungee jumping , which must support the mass of people as they jump off structures such as bridges. When a person reaches the end of a cord, the cord deflects Elastic deformation elastical ly and stops the person s descent. This creates a large axial stress in the cord. A fraction of the elastic potential energy stored in the cord is typically transferred back to the person, throwing the person upwards some fraction of the distance ..., but have a torque that varies significantly over time.

In mathematics , the cyclic category or cycle category or category of cycles is a category theory category of finite cyclically ordered set s and degree 1 maps between them. It was introduced by harvtxt Connes 1983 . Definition The cyclic category has one object sub n sub for each natural number n 0, 1, 2, ... The morphisms from sub m sub to sub n sub are represented by increasing functions f from the integers to the integers, such that f x m n f x , where two functions f and g represent the same morphism when their difference is divisible by n . Informally, the morphisms from sub m sub to sub n sub can be thought of as maps of oriented necklaces with m 1 and n 1 beads. More precisely, the morphisms can be identified with homotopy classes of degree 1 increasing maps from S sup 1 sup to itself that map the subgroup Z m 1 Z to Z n 1 Z . Properties The number of morphisms from sub m sub to sub n sub is m n 1 m n . The cyclic category is self dual. The classifying space B of the cyclic category is a classifying space BS sup 1 sup of the circle group S sup 1 sup . Cyclic sets A cyclic set is a contravariant functor from the cyclic category to sets. More generally a cyclic object in a category C is a contravariant functor from the cyclic category to C .
