An analysis of pilot symbol assisted modulation for Rayleigh fading channels (mobile radio)
TLDR
In this paper, the bit error rate in binary-phase-shift-keying (BPSK) and in quadrature phase-shift keying (QPSK), for a tight upper bound on the symbol error rate for 16-QAM was presented.Abstract:
The author presents pilot-symbol-assisted modulation (PSAM) on a solid analytical basis, a feature missing from previous work. Closed-form expressions are presented for the bit error rate (BER) in binary-phase-shift-keying (BPSK) and in quadrature-phase-shift-keying (QPSK), for a tight upper bound on the symbol error rate in 16 quadrature-amplitude-modulation (16-QAM), and for the optimized receiver coefficients. The error rates obtained are lower than for differential detection for any combination of signal-to-noise ratio (SNR) and Doppler spread, and the performance is within 1 dB of a perfect reference system under slow-fading conditions and within 3 dB when the Doppler spread is 5% of the symbol rate. >read more

Adaptive PSAM in Cross-Layer Combining of AMC and ARQ
TL;DR: Different schemes about power arrangement and spacing allocation of pilot symbols in cross-layer design are investigated in this paper to maximize the average spectral efficiency at the physical layer accounting for meeting the target package loss probability at the data link layer.

Channel estimation with amplitude constraint: Superimposed training or conventional training ?
TL;DR: This study shows that with the constraint of total amplitude for each symbol, the conventional PSAM performs better in the high signal-to-noise ratio (SNR) region while at low SNR, the superimposed scheme performs better.

TCMP-a modulation and coding strategy for Rician fading channels
M.L. Moher,J.H. Lodge +1 more
TL;DR: TCMP is a novel modulation strategy for Rician fading channels that multiplexes a time domain pilot sequence with trellis-coded data to permit coherent detection and is shown to provide remarkably robust performance in the presence of fading.

Rayleigh fading compensation method for 16QAM in digital land mobile radio channels
S. Sampei,T. Sunaga +1 more
TL;DR: In this paper, a Rayleigh fading compensation method for 16-QAM was proposed, where second-order interpolation was used for the fading compensation, and the degradation due to the proposed fading compensation was about 2 dB.
