Patent ID: 8542778

Claim:
A method of detecting a receiver timing error with respect to a received signal comprising: expanding the bandwidth of the received signal, wherein the received signal has a period, wherein the expanding of the bandwidth of the received signal comprises expanding the bandwidth of the received signal using a delay of (n/2) times the period, and wherein n is an integer >2; and, determining the timing error based on the bandwidth expanded received signal, wherein the timing error is determined by use of a timing error detector employing at least one delay element; wherein the determining of the timing error comprises: delaying the bandwidth expanded received signal to produce a first delayed output; delaying the first delayed output to produce a second delayed output; subtracting the second delayed output from the bandwidth expanded received signal to produce a subtraction output; extracting a sign from the first delayed output; and, multiplying the sign and the subtraction output to produce the timing error.
