Space-Time Codes for Wireless Optical Communications
A space-time channel coding technique is presented for overcoming turbulence-induced fading in an atmospheric optical heterodyne communication system that uses multiple transmit and receive apertures. In particular, a design criterion for minimizing the pairwise probability of codeword error in a space-time code (STC) is developed from a central limit theorem approximation. This design criterio...
متن کاملSpace-time codes for high bit rate wireless communications: asymptotic performance of space-time random codes
To quantify the diversity gain of Space-Time coding, obtained by increasing the number of transmit and receive antennas, in this paper we use the paradigm of random codes, modelling Space-Time codes as random matrices with zero mean, equal variance and independent entries having a common arbitrary distribution (discrete or continuous). This framework is especially convenient in this situation b...
متن کاملSerial Concatenated Systematic Convolutional Codes for Space Communications
This letter describes the performance of the serial concatenation of two recursive systematic convolutional codes at very low Eb/N0 iteratively decoded with the MAP (maximum a posteriori) algorithm. Index Terms Error correction, Turbo codes _________________ This work was supported in part by the Institute for Telecommunications Research, University of South Australia and the Australian Researc...
متن کاملConcatenated error-correcting entropy codes and channel codes
We propose a general class of concatenated errorcorrecting entropy codes and channel codes. In this way we extend and generalize the existing body of work on iterative decoding of entropy and channel codes. Using the structure and properties of serial concatenated codes, we employ error-correcting entropy codes as the outer code, and a convolutional code as the inner code. The generalization fr...
متن کاملConcatenated Convolutional Codes for Deep Space Mission
In satellite communication deep space mission are the most challenging mission, where system has to work at very low Eb/No. Concatenated codes are the ideal choice for such deep space mission. ISRO is planning to send unmanned mission for Mars and several deep space missions in future to study and detailed understanding of our own universe. This paper basically reviews the concatenated convolut...
