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.]]>Alamouti, S.,1998Damen, M.O., K. Abed-Meraim and J.C. Belfiore,2002Foshini, G.J. and M.J. Gans,1998Mukkavilli, K.K., M. Ionescu and B.
