Abstract: PROBLEM TO BE SOLVED: To provide a system and method for modulation diversity. SOLUTION: The system and method for modulation diversity uses interleaving. Code bits are placed into groups and are then shuffled within each group. An interleaver uses a bit-interleaver solely to achieve m-ary modulation diversity and uses a two-dimension interleaved interlace table and a run-time slot-to-interlace mapping to achieve frequency diversity which provides better interleaving performance without the need for explicit symbol interleaving.

Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate guard bandwidth independent mapping and de-mapping of bandwidth in a wireless communication system.SOLUTION: Broadcast signals can be created as if the whole bandwidth were available, and guard bandwidth can be initialized over the utilized bandwidth, to puncture data existing in the guard bandwidth. Upon decoding the broadcast signals, the size of the guard bandwidth can be predetermined or estimated by allowing a center portion of the signal to be decoded without decoding the guard bandwidth. In this regard, the decoder of the signal need not find exact positions of the guard bandwidth because transforming and decoding the center portion provides a substantial portion of the signal to interpret the signal.

Abstract: PROBLEM TO BE SOLVED: To provide a system and method for facilitating guard bandwidth independent mapping and de-mapping of a bandwidth in a wireless communication system.SOLUTION: To map symbols to a bandwidth independent of guard tones, a broadcast message is encoded into a plurality of broadcast symbols (502); and mapped to the entire bandwidth (504); and the guard tones are zeroed out (506). Then, the broadcast symbols and the guard tones are transformed to a time domain (508), and transmitted as a broadcast signal (510).
