Abstract
In this paper we propose a soft output detector for theMIMO-CDMA systems with permutation spreading. Insuch systems, the spreading waveforms of each transmitantennas are dependent on the data to be transmitted. Inthe proposed system, information bits are convolutionallyencoded prior to being used in a MIMO-CDMA systemwith permutation spreading. Reliability of the detectedbits in the receiver is calculated in the form of LLRs andthen used as the input of a soft input Viterbi decoder. Theperformance of the proposed system is compared toconventional coded MIMO-CDMA systems.
