First Claim
Patent Images
1. A method for bit synchronization in a frequency shift keying (FSK) receiver, the method comprising steps of:
- receiving a training sequence from a transmitter, wherein the training sequence having a plurality of bits;
determining peak values corresponding to each of the received plurality of bits of the training sequence in a corresponding test range of each of the received plurality of bits; and
determining a starting point of a next bit received by the FSK receiver after the training sequence according to the peak values;
wherein, the starting point of the next bit received by the FSK receiver is determined by summing the peak values, dividing the summation by a number of the received plurality of bits of the training sequence, and then adding a bias value.

Abstract
An algorithm for bit synchronization in a frequency shift keying (FSK) receiver. In the algorithm, a training sequence is received from a transmitter. The training sequence has a plurality of bits. A starting point of a next bit received by the FSK receiver after the training sequence is determined according to peak values of the bits of the training sequence.
