PROBLEM TO BE SOLVED: To provide a system for communicating messages in an environment which is subjected to fading. SOLUTION: At a transmitting side, a checksum (CSM) is specified for encoded and formatted data and the checksum (CSM) is added to an address code word (ADD) which is concatenated with encoded and formatted message code words (M1, M2, M3) to form a message. A receiver decodes and stores the concatenated code words in response to recognizing its address code word. As each code word is stored, substantially and simultaneously a checksum is computed for the messages assembled so far and is compared to the checksum in the address code word. If and when they are equal, it is concluded that a complete message has been received and further analysis of the stored message is terminated. COPYRIGHT: (C)2006,JPO&NCIPI
