Generating pilot signals for synchronization and/or channel estimation in a cellular communication system using code division multiple access modulation technology

摘要

The table illustrates the frame synchronization words C1 - C ith according to a preferred embodiment of the present invention where each word comprises L number of sequences of pilot bits from a prescribed bit position of the N pilot bits from each slot. The number of synchronization words equals 8, the number of slots equals 16 and the number of pilot bits is between 4 and 16. The pilot symbol of each slot is received, the receiving position of the symbols are correlated to a corresponding pilot sequence and the correlation results are combined and summed. Independent claims are included for a method for eliminating side lobes in a communication channel, for a method of establishing a communication channel, for a communication link and for a collator circuit.
