Patent ID: 8594247

Claim:
A transmitter, comprising: a plurality of transmit antennas; and at least one transmit signal processor configured to: apply forward error coding to a signaling message to generate a coded signaling message; M-ary Phase Shift Key (MPSK) map the coded signaling message to produce a MPSK mapped coded signaling message; encode symbols of the MPSK mapped coded signaling message using Differential Space-Time Block Coding (D-STBC) in a time direction to generate encoded symbols; map the encoded symbols of the MPSK mapped coded signaling message onto a plurality of sub-carriers within an Orthogonal Frequency Division Multiplexed (OFDM) frame comprising a plurality of OFDM symbols; and transmit the encoded symbols on the plurality of transmit antennas, with the encoded symbols being transmitted at an increased power level relative to other symbols within the OFDM frame as a function of channel conditions.
