Abstract / Description of output

In this paper we discuss the outage capacity of multihop networks employing terminals with multiple antennas. We discuss the performance of several novel relaying configurations and signalling algorithms for either limited feedback or non-feedback channels. Three relaying types are considered, namely analogue relaying, digital relaying and hybrid relaying. We find that digital selective relaying outperforms all other relaying configurations considered here while requiring the highest signalling overhead. The matched filter based hybrid relaying scheme appears to be a good suboptimum choice for its good performance and low signalling overhead in the multiple relay scenario. We also find that for hybrid relaying schemes, the MMSE algorithm, which is usually applied in conventional MIMO systems, might not give effective performance improvement when it is applied at relays
