In this paper, the problem of receive Antenna Selection (AS) is considered, in a multiple antenna communication system having a single Radio Frequency (RF) chain at the receiver. The AS is performed on a per-packet basis, and AS decisions are based on noisy estimates of the channel gains obtained using pilot symbols embedded in the data packet for coherent demodulation, along with the receiver's knowledge of the time correlation of the channel. The problem is posed as a Partially Observable Markov Decision Process (POMDP) with the goal of minimizing the average Packet Error Rate (PER).
