Space-time block codes versus space-time trellis codes

ICC 2001. IEEE International Conference on Communications. Conference Record (Cat. No.01CH37240), 2002
Two outstanding examples of transmit diversity schemes for the multiple-antenna flat-fading channel are space-time block coding (STBC) and space-time trellis coding (STTC). We compare the performance of STBC and STTC in terms of the frame error rate keeping the transmit power, spectral efficiency and number of trellis states fixed.

On Distributed Space-Time Coding

2007 IEEE Wireless Communications and Networking Conference, 2007
Codes construction for cooperative diversity in ad-hoc networks is considered. In the context of decoded-and-forward strategy, a new class of distributed space-time codes is proposed. This class is tolerant to timing offsets between the different relays, which is crucial for relaying over ad-hoc networks that lack a timing reference. The proposed codes
