Spectral efficient protocols for half-duplex fading relay channels
B. Rankov,Armin Wittneben +1 more
TL;DR: Two new half-duplex relaying protocols are proposed that avoid the pre-log factor one-half in corresponding capacity expressions and it is shown that both protocols recover a significant portion of the half- duplex loss.
Proceedings ArticleDOI
Achievable Rate Regions for the Two-way Relay Channel
B. Rankov,Armin Wittneben +1 more
TL;DR: It is shown that a combined strategy of block Markov superposition coding and Wyner-Ziv coding achieves the cut-set upper bound on the sum-rate of the two-way relay channel when the relay is in the proximity of one of the terminals.
Journal ArticleDOI
Power Allocation Schemes for Amplify-and-Forward MIMO-OFDM Relay Links
I. Hammerstrom,Armin Wittneben +1 more
TL;DR: A two-hop MIMO-OFDM communication scheme with a source, an amplify-and-forward relay, and a destination is considered and a high SNR approximation of the SNR at the destination leads to rates which are quite tight to the optimum.
Proceedings ArticleDOI
Spectral Efficient Signaling for Half-duplex Relay Channels
B. Rankov,Armin Wittneben +1 more
TL;DR: This work considers a relaying protocol where two half-duplex relays alternately forward messages from a source terminal to a destination terminal (two-path relaying), and it is shown that the protocol can recover a significant portion of the halfduplex loss.
Proceedings ArticleDOI
UWB for noninvasive wireless body area networks: channel measurements and results
TL;DR: In this paper, the authors presented UWB channel measurements from 3 to 6 GHz for a body area network (BAN) in an anechoic chamber and an office room.
