摘要： The invention relates to supporting an acquisition of a signal, wherein the signal comprises a sequence of complex valued samples, wherein the acquisition comprises an integration of the complex valued samples in subsequent integration intervals, and wherein the signal may be subject to a frequency drift. In order to enable an improved acquisition, a phase angle is estimated in the signal in a respective integration interval (step 504). The samples are adjusted based on the estimated phase angle in a respective integration interval (step 505). Only the adjusted samples from a plurality of integration intervals are then integrated (step 507, 508).

摘要： Code synchronization is acquired as a part of receiving and decoding a spread spectrum transmission. There are received a number of signal samples that constitute a signal sample sequence. It represents a length of a received signal spread with one full length of a pseudorandom sequence used as a spreading code. The signal sample sequence is augmented at least at one end with at least one additional symbol, which produces a padded signal sample sequence. The padded signal sample sequence is in turn correlated with a locally produced sample sequence that comprises code samples representing a known form of said spreading code (202). The result of said correlating is used as a basis for acquired code synchronization.
