Abstract

A new performance criterion called harmonic mean of squared product distance (HMSPD) to design codes for an independent fading channel is proposed. HMSPD criterion is derived based on probability of error analysis using union bounding technique. It is applied to obtain the optimum pre-rotating matrices for a BPSK modulated transmission over a fast fading channel. The optimum $2 \times 2$ pre-rotating matrix is derived and its BER performance is compared with that of the one designed based on the popular criterion of maximizing the minimum product distance of the constellation. The new criterion gives a slightly better performance than the earlier one and it is also analytically tractable for extending to higher dimensions. Simulations are carried out and they indicate improvement in performance.
