SPREADING CODE ALLOCATING METHOD, DESPREADING METHOD, TRANSMITTER, RECEIVER, COMMUNICATION DEVICE, WIRELESS BASE STATION DEVICE, AND MOBILE TERMINAL |
摘要 |
When a two-dimensional spread code, with which spreading is made in time and frequency directions, is allocated to each channel, spread codes at least one of time and frequency directions of which are mutually orthogonal, and with which despreading can be made with spreading factors that are smaller than the original spreading factors in the respective directions are recognized as selection targets, and a spread code to be allocated to each channel is determined from among the spread codes recognized as the selection targets. |
