ABSTRACT:
A method for improving reception of a data word to be sent from an origination station to a destination station comprises generating and storing error correction functions for a message word including the data word. Error correction functions are transmitted only if the message word is invalidly received thus offering improved performance over a conventional retry scheme. Interleaving reduces susceptibility to burst noise and altering carrier frequency for retransmissions minimizes effects of noise. The method is especially useful in a system comprising a central receiver and a plurality of physically separated remote transmitters wherein electrical path quality between receiver and transmitters may independently randomly vary.
