Abstract: SYSTEMS AND METHODS ARE PROVIDED FOR THE TRANSMISSION OF WAVEFORMS TO AID CHANNEL ESTIMATION, TIMING SYNCHRONIZATION, AND AGC BOOTSTRAPPING IN A WIRELESS NETWORK (100). THE METHOD INCLUDES INSERTING AT LEAST ONE TDM PILOT SYMBOL LOCATED AT A TRANSITION BETWEEN WIDE AREA AND LOCAL AREA WAVEFORMS TO FACILITATE DECODING OF THE TRANSMISSION BLOCK.

Abstract: THE DISCLOSURE IS DIRECTED TO A MOBILE COMMUNICATION DEVICE (1050) THAT MAY RECEIVE WIRELESS BROADCAST SIGNALS FROM A NUMBER OF DIFFERENT BASE STATIONS OR TRANSMITTERS (120, 130). AS THE LOCATION OF THE DEVICE (106) MOVES RELATIVE TO THE TRANSMITTERS, ONE TRANSMITTER WILL LIKELY BE IDENTIFIED AS THE TRANSMITTER BROADCAST THE STRONGEST, OR HIGHEST QUALITY, SIGNAL. WHEN THAT DETERMINATION IS MADE, THE USER OF THE MOBILE DEVICE (110) IS PRESENTED THE OPPORTUNITY TO SWITCH TO RECEIVING THAT TRANSMITTER?S SIGNAL. BASED ON THE USER'S REPLY, THE DEVICE (106) MAY REMAIN WITH THE CURRENT TRANSMITTER, EVEN THOUGH IT DOES NOT HAVE THE STRONGEST SIGNAL, OR THE DEVICE (106) MAY BE CONFIGURED TO ACQUIRE AND START RECEIVING THE NEW TRANSMITTER'S, SIGNAL. THE MEASURING OF THE QUALITY OF A TRANSMITTER'S SIGNAL MAY BE BASED ON A COMPOSITE SCORE THAT COMBINES A NUMBER OF INDIVIDUAL MEASUREMENTS MADE OVER A PREDETERMINED PERIOD OF TIME.
