Abstract  Abstract

Each base station transmits a TDM pilot 1 having a plurality of instances of the pilot-1 sequence generated with the PN1 sequence and a TDM pilot 2 having one or more instances of the pilot-2 sequence generated with the PN2 sequence. Each base station is assigned a specific PN2 sequence that uniquely identifies that base station. The terminal uses the TDM 1 pilot to detect the presence of the signal and the TDM 2 pilot to identify the base station and obtain the correct timing. For signal detection, the terminal performs a delay correlation on the received sample and determines if a signal is present. If a signal is detected, the terminal directly correlates the received sample with the PN1 sequence for K1 different time offsets and identifies the K2 strongest TDM 1 pilot instances. For time synchronization, a direct correlation is performed on the received sample with the PN2 sequence to detect the TDM pilot.
