RECEPTION OF MULTIPLE CODE LENGTH CDMA TRANSMISSIONS |
摘要 |
<p>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. The result of said correlating is used as a basis for acquired code synchronization.</p> |
