Maximam Diversity and Full Rank Space-Time Block Code Based on Orthogonal Polynomials

R. Krishnamoorthy and K. Selvakumar

Abstract:
In this research a new coding technique for Space Time Block Code (STBC) in terms of code operator, that could effectively handle the multipath fading (over rayleigh fading channel) is proposed. The proposed coding technique has been built around a set of carefully chosen orthogonal polynomials. The proposed coding scheme exploits the maximum diversity order for a given number of transmit and receive antennas subject to the constraints of having a simple decoding algorithm. The proposed scheme is similar to the generalized STBC. In the simulation work Phase Shift Key (PSK) and Quadrature Amplitude Shift Key (QASK) are used and perfect channel knowledge is assumed. At the receiver end, we use Maximum Likelihood (ML) decoding. This proposed coding technique results in a full diversity code with high coding advantage.
