We investigate and evaluate the application of the soft information in the detection of cooperative spatial multiplexing (CSM) systems. The destination detects the signals transmitted from the relays with successive interference cancellation (SIC) whose performance suffers from the error propagation. The traditional detection methods assuming that the prior-detected symbols are correct, none of them...
This paper analyzes the performance measures of amplify-and-forward (AF) relaying over non-identical Nakagami-m fading channel. The exact probability density functions (PDFs) of total signal-to-noise ratio (SNR) for variable gain relaying and fixed gain relaying are deduced, and the theoretical formulas of moment generating function (MGF) and moments for fixed gain relaying are presented. Since the...
In this paper, we propose a hybrid receiver scheme called FDE-PPIC, which combines minimum-mean-square-error frequency domain equalization (MMSE-FDE) with multistage partial parallel interference cancellation (P-PIC), for the downlink of single-carrier cyclic-prefix code division multiple access (CP-CDMA) system over frequency-selective channels. MMSE-FDE instead of conventional RAKE receiver is utilized...
Cooperative transmission is an emerging communication technique that takes advantages of the broadcast nature of wireless channels. However, due to low spectral efficiency and the requirement of orthogonal channels, its potential for use in future wireless networks is limited. In this paper, by making use of multiuser detection (MUD) and network coding, cooperative transmission protocols with high...
