This paper investigates linear beamforming techniques in relay networks with one source and multiple relays and destinations. The goal is to determine the beamforming matrix so that the signal to noise plus interference ratio at the destination is maximized while respecting power constraints. The considered power constraint here is a total (source and relays) maximum constant power. The key point...
This paper addresses the problem of transmitting data to multiple mobile stations using a decode-and-forward strategy. Precoding vectors are used in relays to cancel out multiple access interference at the mobile stations. Statistical distribution of signal to noise ratio (SNR) is approximated by an expectation maximization algorithm. Based on this distribution, system performance is evaluated for...
