—In this work, 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(More)
—Ultra-dense (UD) wireless networks where the number of remote radio heads (RRHs) could exceed the number of served users, and cloud radio access networks (CRAN) where joint signal processing is performed at a central processor (CP) are two promising network architectures for the emerging fifth-generation (5G) wireless communication systems. By jointly(More)

—Cloud radio access network (CRAN), in which joint signal processing is performed at a central processor (CP), provides a cost-effective way to achieve network densification in emerging wireless communication systems. In such an ultra-dense CRAN (UD-CRAN), the number of remote radio heads (RRHs), typically employed as simple relay nodes and distributed in a(More)
—This paper considers the problem of receive antenna selection (AS) in a multiple-antenna communication system having a single radio-frequency (RF) chain. The AS decisions are based on noisy channel estimates obtained using known pilot symbols embedded in the data packets. The goal here is to minimize the average packet error rate (PER) by exploiting the(More)
—This paper considers antenna selection (AS) for packet reception at a receiver equipped with multiple antenna elements but only a single radio frequency chain. The receiver makes its AS decisions based on noisy channel estimates obtained from the training symbols (pilots). The time-correlation of the wireless channel and the results of the link-layer error(More)
