One of the simplest forms of forward error correction code is the repetition code. With an N repetition code the same bit is sent N times and the decoder decides in favor of the bit that is detected on majority of trials (assuming N is odd). For a BPSK transmission scheme, determine the BER performance of a 3-repetition code.
