Abstract :
An analytic expression for the bit error probability upper bounds of rate-¿ convolutional codes in conjunction with QPSK modulation and maximum-likelihood Viterbi decoding on the fully interleaved Rayleigh fading channel is presented. The given expression is evaluated numerically for selected rate-¿ optimum convolutional codes together with QPSK.
