<p>A device and method for bit-interweaving are provided to process bit-interweaving of the HSDPA channel in the HSPA+ of WCDMA system. The said device includes high layer control information reading module, interweaver number computing module, bit number of single channel computing module, data reading module, bit data assigning module, bit-interweaving writing module, bit-interweaving module, bit-interweaving reading module and bit combining module. The Said method comprises the following steps: reading the high layer control information including modulating mode and channel number; determining the number <SUB/>of orthogonal interweavers and bit number <SUB/>of single channel for every channel; writing U data into <SUB/> interweaver of <SUB/> in term of the line according to the said modulation mode respectively; interweaving the data in every interweaver; reading the bit data of single channel from <SUB/> interweavers alternately and combining the bit data of single channel into U bit data. By means of the device and method, HSPA+ system can support the high level modulate mode such as 64 QAM and can be compatible with current system absolutely.</p> |
