In this paper, we use the replica method originally developed in statistical physics to investigate the asymptotic sum-rate of a Gaussian antenna-array-based multiple-input multiple-output (MIMO) multiple-access (MA) wireless channel having spatial correlations at both the transmitters and the receiver. Through numerical experiments, the asymptotic solution(More)
In this paper, we propose an iterative equalization algorithm for the TDS-OFDM/ZP-OFDM system to mitigate the inter-symbol interference (ISI) incurred by channels with large delay spread. The time-domain signal components polluted by the ISI are replaced with the reconstructed ones, which are generated from the the channel impulse response and the data(More)
We use the replica method originally developed in statistical physics to investigate the asymptotic sum-rate of a Gaussian antenna-array-based multiple-input multiple-output (MIMO) multiple-access wireless channel having spatial correlations at both the transmitters and the receiver. The asymptotic solution is not only rigorously valid for systems with(More)
—Inspired by the success of the low-density parity-check (LDPC) codes in the field of error-control coding, in this paper we propose transforming the downlink multiuser multiple-input multiple-output scheduling problem into an LDPC-like problem using the normal graph. Based on the normal graph framework, soft information, which indicates the probability(More)
