<p>AN ASSIGNMENT SCHEME EXPLOITS THE MEDIA ACCESS CONTROL (MAC) LAYER PROTOCOL FEATURES UNDER VARIOUS MAC LAYER CALL SCENARIOS. IN ONE EMBODIMENT, THE HAMMING DISTANCE BETWEEN PAIRS OF CRITICAL DATA UNITARE ASSIGNED TO CODEWORDS WITH A MINIMUM DISTANCE OF DMIN2 = 8 BITS. THEREBY INCREASING THE HARD DECISION ERROR CON-ECTING CAPABILITY FROM 1 BIT TO 3 BITS WHEN DECIDING BETWEEN THESE PAIRS OF DATA UNITS. THE METHOD FOR ASSIGNING DATA UNIT IDENTIFICATION (DUID) CODES BY A RADIO (102, 103 AND 104) OPERATING WITHIN A WIRELESS COMMUNICATION SYSTEM (100) INCLUDES DETERMINING BY THE RADIO (102, 103 AND 104) WHETHER AN EXPECTED BURST IS A 4 VOIEE BURST WITH ENCRYPTION SYNCHRONIZATION SIGNALING (4V); WHEN THE EXPECTED BURST IS 4V, DECODING THE DUID WITHIN THE RECEIVED BURST USING AN INCREASED MINIMUM DISTANCE; AND WHEN THE EXPECTED BURST IS NOT 4V, DECODING THE DUID WITHIN THE RECEIVED BURST USING A MINIMUM DISTANCE.</p> |
