Abstract :
Capacity of MIMO LAS-CDMA using multi-code detection under the interference covariance unknown and interference covariance known were studied in the paper. According to the zero correlation windows property of LS codes, capacities with two cases are the same, and they all equivalent to that of multi-user detection (MUD). Numerical results show that: not like conventional CDMA system having capacity platform as SNR increasing, the capacity based on LS code is linear increased with SNR.
