Space-time block codes versus space-time trellis codes
ICC 2001. IEEE International Conference on Communications. Conference Record (Cat. No.01CH37240), 2002Two 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.

Convolutional Space-Time Codes
2006 Canadian Conference on Electrical and Computer Engineering, 2006Space-time codes are usually generated using a generator matrix with 2 columns and mod 4 operations for QPSK modulation with two transmit antennas. A Z4 convolutional code has also been used to represent these space-time codes. Another way of representing them is to use a conventional binary convolutional code of rate 2/4.

On the performance of space-time codes
Proceedings of the IEEE Information Theory Workshop, 2003This paper provides an overview of the results in a recent journal submission by the same authors. The first part of that paper studies the pairwise error probability of codewords (PEP) of a space-time code over a quasistatic channel, using an approach that allows both known and unknown channel cases to be considered simultaneously.

On Distributed Space-Time Coding
2007 IEEE Wireless Communications and Networking Conference, 2007Codes 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

Rateless codes are good codes of infinite length that have the property that prefixes of such codes are themselves good codes. This makes them attractive for applications in which the channel quality is uncertain, where systems transmit as much of a codeword as necessary for decoding to be possible.
