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

Channel estimation for an SVD-MIMO System
TL;DR: It is shown that tracking of the CSI provides a better estimate of the MIMO decoding matrix than direct tracking of matrix itself.

Performance of a Linear-Detector Joint Radar-Communication System in Doubly Selective Channels
TL;DR: A framework for cooperative operation of single-input single-output bistatic radar and wireless communication systems is developed, a low-complexity linear minimum mean square error (LMMSE) optimal pilot symbol aided modulation scheme is adopted, and the achievability region of the joint radar-communication system designed for simultaneous operation in a wireless channel that is both frequency and time-selective is shown.

Performance analysis of coded OFDM on fading channels with non-ideal interleaving and channel knowledge
TL;DR: The coded bit-error rate (BER) in an orthogonal frequency-division multiplexing (OFDM) system in a Rayleigh-fading channel is investigated and it is shown that this can be the case for channels with few propagation paths.

Error Probability of DF Relaying with Pilot-Assisted Channel Estimation over Time-Varying Fading Channels
TL;DR: This paper investigates the error rate performance of a cooperative network with adaptive decode-and-forward (DF) relaying over time-selective frequency-flat Rayleigh-fading channels and derives an exact closed-form expression for the average bit/symbol error rate.

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.
