Patent ID: 7991040

Claim:
A method for reducing a peak to average ratio (PAR) of a transmit waveform, the method comprising: obtaining a primary scrambler sequence comprising a sequence of data bits configured to randomize data from a plurality of symbols; generating a secondary scrambler sequence comprising a sequence of data bits shorter in length than the primary scrambler sequence and being configured to randomize data to be transmitted within a single symbol, wherein the length of the secondary scrambler sequence is based on a length of the data to be transmitted in the single symbol; selectively combining the primary and secondary scrambler sequences to produce a PAR reduction sequence based on whether a PAR control signal is in a first state or a second state, wherein the PAR reduction sequence comprises the primary scrambler sequence when the PAR control signal is in the first state, and the PAR reduction sequence comprises the combined primary and secondary scrambler sequences when the PAR control signal is in the second state.
