Patent ID: 7308041

Claim:
A method for transmitting a wireless signal using orthogonal frequency division multiplexing, the method comprising: modulating the wireless signal using digital phase modulation; sampling the wireless signal after modulation to generate a plurality of sampled values of the modulated wireless signal; determining at least one amplitude value of the wireless signal using the plurality of sampled values; comparing the at least one amplitude value to a predefined threshold to obtain a correction signal; determining a phase of the wireless signal; providing the correction signal with the phase of the wireless signal; subtracting the correction signal from the wireless signal after providing the correction signal with the phase of the wireless signal to reduce the amplitude values of the wireless signal that lie above the predefined threshold to a value of the threshold to generate a corrected wireless signal; pre-equalizing the corrected wireless signal; converting the pre-equalized wireless signal into an analog wireless signal using at least one digital-analog converter; amplifying the analog wireless signal; and transmitting the amplified wireless signal.
