MMSE Optimal Space-Time Block Codes from Crossed Product Algebras
Design of Space-Time Block codes (STBCs) for Maximum Likelihood (ML) reception has been predominantly the main focus of researchers. However the ML decoding complexity of STBCs become prohibitive large as the number of transmit and receive antennas increase. To solve this problem, orthogonal designs, single symbol ML decodable and double symbol ML decodable STBCs have been proposed in the liter...
متن کاملDiagonal algebraic space-time block codes
We construct a new family of linear space-time block codes by the combination of rotated constellations and the Hadamard transform, and we prove them to achieve the full transmit diversity over a quasi-static or fast fading channels. The proposed codes transmit at a normalized rate of 1 symbol/sec. When the number of transmit antennae n = 1, 2 or n is a multiple of 4 we spread a rotated version...
متن کاملOn Fast-Decodable Algebraic Space-Time Codes
In the near future, the 5th generation (5G) wireless systems will be established. They will consist of an integration of different techniques, including distributed antenna systems and massive multiple-input multiple-output systems, and the overall performance will highly depend on the channel coding techniques employed. Due to the nature of future wireless networks, space– time codes are no lo...
متن کاملOn diagonal algebraic space-time block codes
Theoretical and practical aspects of diagonal algebraic space-time block codes over n transmit andm receive antennae are examined. These codes are obtained by sending a rotated version of the information symbols over the principal diagonal of the n × n space-time matrix over n transmit antennae and n symbol periods. The output signal-to-noise ratios of two pre-decoding filters and two decoding ...
متن کاملOn Diagonal Space-Time Codes Using Algebraic Rotations
Theoretical and practical aspects of diagonal algebraic space-time block codes over n transmit and m receive antennae are examined. The output signal-to-noise ratios of two pre-decoding filters and two decoding algorithms are derived. Analysis of the information loss incurred by using the codes considered is used to clarify their structures, and the expected performances. Different algebraic re...
