Novel Zero Circular Convolution Sequences for Detection and Channel Estimations

Multiuser communication systems or multiple access scheme favor sequences possessing the ideal periodic cross-correlation function (PCCF) property. In comparison, channel estimation, equalization, and synchronization applications auto-correlation (PACF) However, there is no set of both PCCF PACF properties simultaneously, where balance each other. this work, property are used as base sequences. Then, a modulation technique applied upon these to construct zero circular convolution (ZCC) within which an arbitrary pair two possesses Compared with least squares (LS) minimum mean squared error (MMSE) algorithm, simulation results show that estimation performance ZCC better than MMSE LS algorithms, computational complexity algorithm same but far lower algorithm. This first study on reported in literature, their fundamental theorems, properties, construction, investigated. The advantage desired allows be broader range other sets
