Performance Evaluation of Ds-cdma System Using Chaotic Binary Sequences
In this paper generation of binary sequences derived from chaotic sequences defined over Z4 is proposed. The six chaotic map equations considered in this paper are Logistic map, Tent Map, Cubic Map, Quadratic Map and Bernoulli Map. Using these chaotic map equations, sequences over Z4 are generated which are converted to binary sequences using polynomial mapping. Segments of sequences of differe...
متن کاملPerformance Evaluation of Different DS-CDMA Receivers Using Chaotic Sequences
Spreading codes play an important role in multiple access capacity of DS-CDMA system. M-sequences, gold sequences etc., has been traditionally used as spreading codes in DS-CDMA. These sequences are generated by shift registers, which are periodic in nature. So these sequences are less in number and this limits the security. This paper presents an investigation on use of new type of sequences c...
متن کاملPerformance Evaluation of Ds-cdma System Using Matlab
The author evaluated the performance of synchronous DS-CDMA systems over multipath fading channel and AWGN Channel. The synchronous DS-CDMA system is well known for eliminating the effects of multiple access interference (MAI) which limits the capacity and degrades the BER performance of the system. This paper investigated the bit error rate (BER) performance of a synchronous DS-CDMA system ove...
متن کاملPerformance Enhancement of Mc-ds/cdma System Using Chaotic Spreading Sequence
A novel chaotic spreading sequences for multi-carrier direct sequence code division multiple access (MCDS/CDMA) system is proposed. With this spreading sequence in the MC-DS/CDMA system, the effect of multiple access interference can be mitigated by choosing the spreading sequences with appropriate crosscorrelation properties. The performance of the system is assayed in the multiuser environmen...
متن کاملPerformance Analysis of MIMO MC-DS/CDMA System Using Chaotic Spreading Sequence
This paper presents a novel chaotic spreading sequence for multiple input multiple output multi-carrier direct sequence code division multiple access (MIMO MCDS/CDMA) systems. The effect of multiple access interference can be mitigated by choosing the spreading sequences with appropriate cross-correlation properties. The performance of the system is analysed in multiuser scenario with the aid o...
