Patent ID: 8050295

Claim:
A method comprising: dividing a transmission bit sequence into an even-numbered bit sequence and an odd-numbered bit sequence, bits adjacent to each other in the transmission bit sequence being separated from each other by a bit time; generating first sampled values by sampling at a sampling rate a first fundamental wave that is based on the even-numbered bit sequence, the sampling of the first fundamental wave being performed within a first sampling window having a time duration that is based on the bit time and the sampling rate; generating second sampled values by sampling at the sampling rate a second fundamental wave that is based on the odd-numbered bit sequence, the second fundamental wave being shifted by a time period relative to the first fundamental wave, the sampling of the second fundamental wave being performed within a second sampling window having the time duration of the first sampling window; summing the first sampled values and the second sampled values to form an output value sequence; converting the output value sequence into analog values; and filtering the analog values to obtain a baseband signal.
