On the Energy Detection of Unknown Signals Over Fading ChannelsAbstract—This letter addresses the problem of energy detection of an unknown signal over a multipath channel. It starts with the no-diversity case, and presents some alternative closed-fo

In this survey article, we compare the performance of single transmit antenna
selection (TAS) systems with different kinds of receiver schemes. These
systems include the TAS/switch-and-examine combining (TAS/SEC), TAS/SEC
with postselection (TA

Abstract—Selection combining cascaded with maximum-ratio
combining (SC/MRC), which is particularly useful when site
diversity is available, combined with low-density parity-check
(LDPC) codes is able to combat the effects of fading. The biterro

In this paper, an Alamouti-coded decode-And-forward protocol with optimum relay selection for three-user one
destination cooperative communications is investigated. Particularly, we design the new protocol that allows the
source node retransmitti

In this paper we uate the performance of cooperative spectrum sensing (CSS) where
each cognitive radio (CR) employs an improved energy detector (IED) with multiple antennas and
uses selection combining (SC) for detecting the primary user (PU) in

In millimetre wave (mm-wave) communications, hybrid precoding is
preferred which uses much less number of RF chains compared with
the number of antenna elements. The conventional method selects the
beamforming vectors at base station (BS) and t
