i am doing project on watermarking using spread spectrum. watermark signal is text signal. to encode this binary signal i am using BCH encoder. this encoded watermark is supposed to converted into level 1 and -1 corresponding to 1 and 0. but after encoding this watermark signal can not be converted into +1 and -1. because it is no longer a integer but a Galois array.I want convert encoded binary watermark signal into +1 and -1.
