Abstract
A method and system for detecting collision of transmitted signals in a random-access, multiple-path communication system utilizes a packet coding arrangement where a transmitting transceiver terminal assembles a plurality of packets into a coded transmit block. Each transmit block is coded with an error detection code, or assigned time slots, so that a routing controller will discard an entire transmit block if any of the packets are not properly decoded. Each transmit block further includes a self-addressed packet, wherein receipt of the self-addressed packet by the transmitting terminal indicates that no collision has occurred. Thus, the present invention does not require any additional circuitry or control of the routing controller, nor transmission of an acknowledgement signal in order to detect collision of transmitted signals.
