ABSTRACT:
A radio communication system (100) includes a system controller (102) for encoding data information to generate data messages which have periodic error protection at one or more burst error frequencies. The system controller (102) transmits one or more of the data messages to at least two transmitters (103) for simultaneous transmission of the one or more data messages. The first and second transmitters (103) have radio carrier frequencies which are offset by an offset frequency which is substantially equivalent to one of the one or more burst error frequencies. A selective call receiver (106) receives and decodes a radio signal including a data message having periodic burst errors at the offset frequency and wherein the data message includes encoding which provides substantial periodic burst error protection at the offset frequency.
