Performance Analysis of a Full-Duplex Cooperative Diversity Scheme with Partial Channel Knowledge at the Cooperating Nodes
Main Article Content
Abstract
We propose a cooperative diversity scheme for a communication system consisting of NT cooperating nodes that receive log2(NT) feedback bits from the destination node on the channel state information. This information is used appropriately to obtain cooperative diversity and signal-to-noise ratio (SNR) gains. A simple linear detector and an interference cancelation detector are proposed. It is shown that their error rates are quite close to that of the maximum likelihood detector. An upper bound for the average bit error probability for binary phase-shift keying (BPSK) modulation over a Rayleigh fading channel is derived. In addition, through computer simulations, it is verified that the proposed scheme offers a good error performance when the inter-user channel SNR is high or when the inter-user channel has a well-defined line-of-sight component. In other words, the new scheme becomes interesting when the cooperating nodes are close to each other.
