Concatenated space-time block codes and TCM, turbo TCM, convolutional as well as turbo codes
Space-time block codes provide substantial diversity advantages for multiple transmit antenna systems at a low decoding complexity. In this paper, we concatenate space-time codes with Convolutional Codes (CC), Turbo Convolutional codes (TC), Turbo BCH codes (TBCH), Trellis Coded Modulation (TCM) and Turbo Trellis Coded Modulation (TTCM) schemes for achieving a high coding gain. The associated p...
متن کاملConcatenated Space-Time Block Codes and Turbo Codes with Unstructured Interference
The performance of space-time block codes in providing transmit diversity is severely degraded when strong localized interference is present. This problem is addressed by investigating a recently proposed coherent space-time block code decoding algorithm for unknown interference suppression. The algorithm assumes a Gaussian noise and interference approximation and is based on a cyclic-based max...
متن کاملSpace-Time Turbo Codes
Introduction: Recently, there has been a surge of interests in the design of the so called \space{time" codes which take advantage of both the spatial diversity provided by multiple antennas and the temporal diversity available with time{varying fading. The previous proposed space{time codes were mainly based on trellis codes or orthogonal block codes. In those codes, the number of transmitter ...
متن کاملTurbo Equalization of Serially Concatenated Systematic Convolutional Codes and Systematic Space Time Trellis Codes
A novel turbo equalization arrangement is proposed, which is constituted by a serially concatenated systematic convolutional codec and a systematic space time trellis code (CC-SSTTC) assisted scheme. The BER performance of this scheme using various interleaving sizes was characterised over an equal-power twopath Rayleigh fading channel. After eight turbo equalization iterations, an interleaving...
متن کاملDifferential space-time turbo codes
Serial concatenation of simple error control codes and differential space-time modulation is considered. Decoding is performed iteratively by passing symbol-wise a-posteriori probability values between the decoders of the inner space-time code and the outer code. An extrinsic information transfer analysis is used to predict thresholds for outer convolutional codes of various memory orders and a...
