IDMA can be regarded as a special case of CDMA, where the spreading can be done by an arbitrary low rate channel code equal for all users and the separation can be done by user-specific interleavers. In this paper, we provide the anti-jamming performance analysis of partial band for IDMA systems. First, we investigate the basic principle of IDMA briefly. Then introduce the generation of the partial...
Interleave-division multiple access systems (IDMA) has been extensively studied. In this paper, we present the performance analysis of anti-jamming for IDMA systems. The theoretic analysis and simulation results show that the performance of anti-jamming for IDMA systems is related to spread gain, code-bit rate, and the number of iterations, respectively. And our research work can provide a reference...
In this paper, we propose a hybrid multiple access scheme which combines interleave division multiple access (IDMA) and code division multiple access (CDMA), therefore, we refer to this scheme as IDMA/CDMA. We employ IDMA technique as the uplink transmission and CDMA technique as the downlink transmission. Thus, IDMA/CDMA can achieve a very simple chip-by-chip iterative multi-user detection (MUD)...
In this paper, we propose a fast converging multiuser detection for interleave-division multiple access (IDMA) system based on time-reversal (TR) technique. The proposed algorithm uses the time-reversed version of the channel impulse responses (TR-CIR) obtained from the uplink to process the received signal before the elementary signal estimator (ESE). With the help of the weak correlation of fading...
