<p>A method for analyzing the channel using the preceding slot synchronization sequence is provided. The method of the invention is for operating a receiver (100) receiving a signal (102) frame in a dynamic channel wherein the signal frame includes a plurality of slots (104, 106, 108, 110, 109), each including a plurality of data bits. Each of the slots further includes a synchronization sequence wherein at least a predetermined one of the slots (104) is assigned for the receiver. The preceding slot (108) following the receiver assigned slot includes a varying synchronization sequence which is selected from a group of predetermined synchronization sequences postulates. The method includes the steps of calculating from the preceding slot synchronization sequence an estimated taps value for each of the synchronization sequence postulates, calculating from the preceding step synchronization sequence a log likelihood metric value C(y,h) for each of the synchronization sequence postulates and selecting the synchronization word postulate having the best metric value.</p> |
