发明名称 Method and apparatus for channel estimation and cell search in cellular communication systems, and corresponding computer program product
摘要 In order to perform, according to a received signal (r), a channel-estimation procedure and a cell-search procedure in cellular communication systems, there are executed at least one first operation of correlation of said received signal (r) with secondary synchronization codes (SSC) and a second operation of correlation of said received signal (r) with known midamble codes (mid, MPL, MPS), whilst said channel-estimation procedure comprises a third operation of correlation of at least part of said received signal (r) with known midamble codes (mid, MPL, MPS), said first, second, and third correlation operations being executed by sending at least part (emidamble) of said received signal (r) to an input of a correlation bank. There are envisaged the operations of: sending, in a first time interval, the received signal (r) to said correlation bank for executing the first operation of correlation of said received signal (r) with secondary synchronization codes (SSC); sending, in a second time interval, at least part (emidamble) of said received signal (r) to said same correlation bank for executing the second operation of correlation of said received signal (r) with known midamble codes (mid, MPL, MPS); sending, in a second time interval, the received signal (r) to said same correlation bank for executing the third operation of correlation of at least part (emidamble) of said received signal (r) with known midamble codes (mid, MPL, MPS). Possible application is in mobile communication systems based upon standards such as UMTS, CDMA2000, IS95 or WBCDMA.
