Abstract  Abstract

PROBLEM TO BE SOLVED: To minimize the amount of pilots to be acquired by both base stations and terminals.

SOLUTION: A base station transmits a TDM pilot 1 having multiple instances of a pilot-1 sequence generated with a PN1 sequence and a TDM pilot 2 having at least one instance of a pilot-2 sequence generated with a PN2 sequence. Each base station is assigned a specific PN2 sequence that uniquely identifies that base station. A terminal uses TDM pilot 1 to detect the presence of a signal and uses TDM pilot 2 to discriminate base stations and obtain accurate timing. For signal detection the terminal performs delayed correlation on received samples performs direct correlation on the received samples with PN1 sequences for K 1 different time offsets and identifies K2 strongest TDM pilot-1 instances. For time synchronization the terminal performs direct correlation on the received samples with PN2 sequences to detect TDM pilot 2.
