Patent ID: 8396178

Claim:
A method for using a synthesized clock frequency to generate a modulated signal, comprising: extracting, by a transmitter, clock frequency f 2 from a wired data connection feeding the transmitter with data clocked at the clock frequency f 2 ; estimating clock frequency error between the clock frequency f 2 and a clock frequency f 1 derived from a local clock of the transmitter; adding the clock frequency error to the clock frequency f 1 , resulting in a synthesized clock frequency f 2 ; using the synthesized clock frequency f 2 to modulate a data stream into a modulated signal; and wherein the modulated signal is OFDM, and using the synthesized clock frequency f 2 to modulate the data comprises using OFDM data symbols of duration associated with the synthesized clock frequency f 2 for creating the modulated signal.
