Abstract— The primary disadvantage of orthogonal frequencydivision multiplexing (OFDM) is the high time-domain peak-toaverage power ratio (PAR) that severely limits the transmitt...
Abstract— This paper is concerned with the end-to-end transmission outage in an OFDM based wireless multi-hop network. The network consists of a source node, a destination node, ...

Abstract—The throughput of multi-hop communication systems can significantly be increased by the application of MIMO concepts. To utilize the physical resources in an efficient...
Abstract—In this contribution we present a decentralized power allocation algorithm for the uplink interleave division multiple access (IDMA) channel. Within the proposed optimal...
