Effective capacity of receive antenna selection MIMO–OSTBC systems in co-channel interference

Abstract

In this paper, delay constrained performance of a multiple-input multiple-output (MIMO) communication system in a dense environment with co-channel interference is investigated. We apply orthogonal space-time block coding (OSTBC) at the transmitter, and for alleviating the high complexity and cost of the MIMO system, receive antenna selection (RAS) scheme is employed in the downlink. Here, for simple and cheap mobile handsets, one antenna is chosen at the receiver in each utilization of the channel. Under these assumptions, a maximum constant arrival rate with the delay qualityof-service (QoS) guarantee in a wireless channel is extracted. We obtain a closed-form solution for the effective capacity of the MIMO-OSTBC channel with the RAS scheme in a quasi-static Rayleigh fading conditions and cochannel interference. After all, the numerical simulations are provided and verified the theoretical results.

Transmission delay minimization in wireless powered communication systems

“…The optimal and suboptimal solutions for the allocated time slots at the DL and UL is obtained under perfect and imperfect selfinterference cancellation. In particular, in [28], the performance of WPC in the presence of statistical queuing constraints with buffer overflow probability [44] is studied. Then, the optimal time allocation for energy harvesting and information decoding operations depends on these constraints is obtained.…”

“…On the one hand, when the average arrival date rate equals to the average service rate, the queue will be steady, and the effective capacity can be interpreted as the maximum throughput of the system in which the queue is in its steady state [22]. On the other hand, the effective capacity can be considered as the maximum service rate [23], or the maximum arrival rate that a service process can handle with the delay requirement [24]. For brevity, the time state index t is dropped.…”
