Patent ID: 8837561

Claim:
A method comprising: a) receiving an initial bit sequence by a receiver; b) locking a local oscillator to a local reference; c) performing automatic gain control (AGC) on the received initial bit sequence; d) performing clock and data recover (CDR) e) activating a Costas loop so as to achieve carrier frequency offset (CFO) lock; f) detecting sign inversion; g) synchronizing the receiver with an end-of-training pattern; h) detecting the end-of-training pattern; wherein the receiver further comprises a transceiver, and wherein the end-of-training pattern further comprise a first end-of-training pattern, and wherein the receiver is operating in a first communications mode prior to the step of synchronizing, and wherein the step of synchronizing further comprises: switching to a second communication mode by the transceiver; and transmitting a second end-of-sequence pattern.
