Error rates of a full-duplex system over EGK fading channels subject to laplacian interference

Abstract

Abstract-This paper develops a mathematical paradigm to study downlink error rates and throughput for half-duplex (HD) terminals served by a full-duplex (FD) base station (BS). Particularly, we study the dominant intra-cell interferer problem that appears between HD users scheduled on the same FDchannel. The distribution of the dominant interference is first characterized via its distribution function, which is derived in closed-form. Assuming Nakagami-m fading, the probability of error for different modulation schemes is studied and a unified closed-form expression for the average symbol error rate is derived. To this end, we show the effective downlink throughput gain, harvested by employing FD communication at a BS that serves HD users, as a function of the signal-to-interference-ratio when compared to an idealized HD interference and noise free BS operation.Index Terms-Dominant interference, Gaussian noise, Laplace interference, Nakagami-m fading, error rate, throughput.

On the unified error performance of PSK modulation schemes over mm‐wave wireless channels affected by carrier phase synchronization errors

“…18,19 The performance over the EGK-distributed channels has been studied further in previous work. [20][21][22][23][24] But the carrier phase synchronization errors in case of coherent modulation schemes employed over EGK-distributed channels have not been considered in literature, [20][21][22][23][24] for performance evaluation. Recently, a fluctuating two-ray (FTR) mm-wave fading model was proposed in Jerez et al, 25 which provides a good empirical fit for outdoor measurements at 28 GHz.…”
