| titleOfInvention | Code division multiplexing mobile communication system, terminal station and base station |
| abstract | In a CDMA system, as the distance between a base station and a terminal station increases, the distribution of reception phases of spread PN codes also increases. In such a case, there arises a problem that it takes a long time to synchronize the PN code. In such a system, a code division multiplexing mobile communication system capable of improving the uplink spreading code, a terminal station, and a base station are provided. In the uplink, a composite code composed of three element codes X, Y and Z that are relatively prime in length As a sync code, Are used as spreading codes. Further, the signal transmission level of the portion related to the synchronization code is set higher than the signal level of the portion related to the spreading code. [Selection] Figure 6 |
