METHOD AND APPARATUS FOR DETECTION OF SYNCHRONIZATION SIGNALS IN WIRELESS NETWORKS

摘要

Various communication systems may benefit from an accurate detection method. The method may include determining correlation values between a first sequence of samples and at least one pre-defined sequence, detecting whether at least one first peak exists by comparing the correlation values with at least one first detection threshold. If the at least one first peak exists, the method may further include performing summing of at least a subset of the correlation values and detecting whether at least one second peak exists by comparing the summed correlation values with a second 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 correlation values between a first sequence of samples and at least one pre-defined sequence; detect whether at least one first peak exists by a comparison of the correlation values with at least one first detection threshold; if the at least one first peak exists,
perform summing of at least a subset of the correlation values; anddetect whether at least one second peak exists by a comparison of the summed correlation values with a second detection threshold.
