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.

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

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.

Concatenated space-time coding
12th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications. PIMRC 2001. Proceedings (Cat. No.01TH8598), 2002The serial concatenation of standard convolutional codes with differential space-time modulation is considered for fast flat fading multiple antenna channels. Decoding is performed iteratively by passing symbol-wise a-posteriori probability information between the decoders of the inner space-time code and the outer convolutional code.

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.
