A binary data stream is encoded using a (63,39) BCH block code and modulated using BPSK (binary phase-shift keying). In the absence of coding, the average bit-energy to single-sided noise-power spectral-density ratio, Eb/No= 7.6 dB. For BPSK you may assume that the bit-error probability is given by P = Q(2E/No), where Q is the Gaussian error function. (i) (ii) (iii) Supposing only the data were transmitted with no coding, what would be the probability of a word error? If the code is used to provide forward-error-correction, what is the probability of a word error? Supposing the code is used to provide only error detection, what would be the probability of an undetectable error?
