ABSTRACT:
Transmitting and receiving apparatus for transmitting data includes a purged code encoder at the transmitter for encoding digital data into constant weight unbalanced codewords representative of the digital data. The constant weight unbalanced codewords containing error correction bits are preferably transmitted as balanced codewords and are decoded at the receiver employing Golay decoders or algebraic decoders to recover the original digital data without the requirement of a large number of matched filter previously employed for decoding.
