Patent ID: 8532204

Claim:
A transmitter, comprising: a first processing block configured to generate a first peak-reducing vector; and a second processing block configured: to receive a first data vector, the data vector comprising a plurality of samples, the first data vector having a first peak with a first index and a first magnitude, a second peak with a second index and a second magnitude that is less than the first magnitude, and a first peak-to-average power ratio, and to generate a second data vector having a second peak-to-average power ratio that is lower than the first peak-to-average power ratio by using the first peak-reducing vector; wherein generating the second data vector includes: generating a second peak-reducing vector by shifting the first peak-reducing vector by a number of samples substantially equal to the first index; generating a third peak-reducing vector by scaling the second peak-reducing vector by a first coefficient, and by further scaling the second peak-reducing vector by a second coefficient; and generating the second data vector by combining the third peak-reducing vector with the first data vector; and at least one of the first processing block and second processing block is implemented by hardware.
