We present a factor graph based design of a receiver for pilotassisted OFDM-IDMA systems transmitting over frequency-selective channels. The receiver performs joint iterative mult...
Abstract--An iterative joint channel estimation, symbol detection, phase recovery and interference cancellation structure is proposed for asynchronous code-division multiple-access...
We propose a joint channel and data estimation scheme which does not require the training data in multicarrier direct-sequence multiple access (MC-DS/CDMA) systems. In order to eli...
Abstract—This paper studies large randomly spread directsequence code-division multiple-access system operating over a block fading multipath channel. Channel knowledge is obtain...
1 — The authors of this paper proposed an iterative expectation-maximization (EM) channel estimation based on a low-density parity-check (LDPC) code-division multiple access rece...
