Information-theoretic multihopping for relay networks

Recent advances in multihopping are extended to relay networks having multiple antennas and multiple sources. As for the single-antenna and single-source case, one can achieve the ergodic capacity of wireless relay networks with phase fading if the relays are in a region near the source terminal, and if information is available only locally. The capacity results further generalize to Rayleigh fading, single-bounce fading, quasistatic fading problems, cases where partial channel knowledge is available at the transmitters, and cases where local user cooperation is permitted. The multisource networks considered are the multiaccess and broadcast relay channels.
