Modulation-adaptive cooperation in Rayleigh fading channels with imperfect CSI
Adaptive modulation can improve the throughput of cooperative communications, which has been shown in previous research. So far the adaptive modulation is applied with respect to ...

Adaptive PSAM in SIMO systems with imperfect CSI in Rayleigh fading channels
In this paper we provide an adaptive modulation approach that uses adaptive pilot symbols which both pilot spacing and power allocation on pilot symbols are optimized in single in...

Asymptotic BER Analysis for MIMO-BICM with Zero-Forcing Detectors Assuming Imperfect CSI
—In this paper, we derive the asymptotic bit error rate (BER) for multiple-input multiple-output bit-interleaved coded modulation (MIMO-BICM) with linear zero-forcing (ZF) receiv...

Optimum and Suboptimum Receivers for Space-Time Coded Systems in Correlated Fading
Abstract — We consider a space-time coded system in a correlated Rayleigh flat fading environment. The channel state information (CSI) is obtained from the known pilot code matr...

Power Allocation in MMSE Relaying over Frequency-Selective Rayleigh Fading Channels
Abstract--This paper develops an amplify-and-forward relaying scheme for multiuser wireless cooperative networks under frequency-selective block-fading. Single-carrier frequency di...
