The pairwise error probability analysis for the i.i.d. Rayleigh fading channel has led us to the product distance (for time diversity) and generalized product distance (for transmit diversity) code design criteria. Extend this analysis for the i.i.d. Rician fading channel.
1. Does the diversity order change for repetition coding over a time diversity channel with the L branches i.i.d. Rician distributed?
2. What is the new code design criterion, analogous to product distance, based on the pairwise error probability analysis?
