Abstract
A method of synchronizing a receiver with a transmitter. The method includes determining number of bits, j, for adjusting a bit stream, where the bit stream is generated from n tones and is dividable into codewords having a codeword length of N bytes, and the number of bits for adjusting the bit stream is determined based upon n and N. The method includes detecting a loss of synchronization indication. In response to detection of the loss of synchronization indication, the method includes adjusting the bit stream by j bits. The method includes determining whether synchronization has been regained. When synchronization has not been regained, the method includes adjusting the bit stream again by j bits. When synchronization has been regained, the method includes terminating adjustment of the bit stream.
