METHOD AND APPARATUS FOR DETECTION OF SYNCHRONIZATION SIGNALS IN WIRELESS NETWORKS

摘要

Various communication systems may benefit from an accurate cell detection method. The method may include determining at least one first correlation value between a first sequence of received samples and at least one pre-defined sequence, determining at least one second correlation value between a second sequence of received samples at a predetermined distance and the at least one pre-defined sequence, wherein the predetermined distance is substantially more than one symbol and substantially less than two symbols, performing summing of at least the at least one first correlation value and the at least one second correlation value to obtain at least one summed correlation value and detecting whether at least one peak exists by comparing the at least one summed correlation value with a detection threshold.

1. An apparatus, comprising:
at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to determine at least one first correlation value between a first sequence of received samples and at least one pre-defined sequence; determine at least one second correlation value between a second sequence of received samples at a predetermined distance and the at least one pre-defined sequence, wherein the predetermined distance is substantially more than one symbol and substantially less than two symbols; perform summing of at least the at least one first correlation value and the at least one second correlation value to obtain at least one summed correlation value; and detect whether at least one peak exists by a comparison of the at least one summed correlation value with a detection threshold.
