Abstract:
1. A method for creating a delay profile, comprising: receiving a CDMA radio signal under a multipath condition; buffering received data corresponding to a first path in a first bank of a storage memory during a first time interval; buffering received data corresponding to a second path in a second bank of the storage memory during a second time interval; simultaneous to buffering the received data corresponding to the second path, reading the received data corresponding to the first path from the first bank and supplying the received data corresponding to the first path to a correlation detector; performing a correlation detection of a symbol sequence using a correlation detector, said symbol sequence being included in said received signal and comprising a repetition of a unit pattern of +1 and −1; performing an in-phase addition using a correlation obtained by the correlation detection, in which said unit pattern is a processing unit; and performing a power calculation of the received signal utilizing a result of the in-phase addition and creating a delay profile.
