Correlation characteristics of binary phase and quadri phase ICMIC spreading sequences
Jiang Ling · Journal of China Institute of Communications · 2001
Binary phase and quadri phase chaotic spreading sequences are produced using iterative chaotic map with infinite collapses(ICMIC) The distribution and correlation characteristics of such sequences are analyzed Simulation results show that they can achieve better performance than binary phase and quadri phase Logistic sequences,quadri phase Chebyshev sequences,m sequences and Gold sequences with same lengths It is very useful in solving key problems related to correlation characteristics in CDMA mobile communications,such as multiple access interference,multi path interference,multi user detection and so on
