Average-rate optimal PSAM transmissions over time-selective fading channels
Enabling linear minimum-mean square error (LMMSE) based estimation of random time-selective channels, Pilot Symbol Assisted Modulation (PSAM) has well documented merits as a fading countermeasure capable of improving bit error rate performance. In this paper, we establish average-rate optimality of PSAM by showing that the insertion of equi-powered and equi-spaced pilot symbols in PSAM transmis...

متن کاملOptimal training for block transmissions over doubly selective wireless fading channels
High data rates give rise to frequency-selective propagation, whereas carrier frequency-offsets and mobility-induced Doppler shifts introduce time-selectivity in wireless links. To mitigate the resulting timeand frequency-selective (or doubly selective) channels, optimal training sequences have been designed only for special cases: pilot symbol assisted modulation (PSAM) for time-selective chan...
متن کاملMaximum Likelihood Timing and Carrier Synchronization in Burst-Mode Satellite Transmissions
This paper investigates the joint maximum likelihood (ML) estimation of the carrier frequency offset, timing error, and carrier phase in burst-mode satellite transmissions over an AWGN channel. The synchronization process is assisted by a training sequence appended in front of each burst and composed of alternating binary symbols. The use of this particular pilot pattern results into an estimat...
