PROBLEM TO BE SOLVED: To provide techniques for randomizing and transmitting digital data. SOLUTION: A system includes: a first plurality of shift registers connected in series each for receiving a first pseudo noise (PN) sequence; a first array of XOR gates each for exclusively ORing bits of a data word to be transmitted using the first shift registers; a second array of XOR gates connected in parallel each for receiving a second PN sequence and XORing bits of a data word; a second plurality of shift registers connected in series each for receiving the first PN sequence; a third array of XOR gates each for XORing bits of a transmitted data word using the second shift registers; and a fourth array of XOR gates connected in parallel each for receiving the second PN sequence and XORing bits of a data word.
