METHOD AND APPARATUS FOR ADJUSTING POWER GAIN FACTORS OF CODE CHANNELS IN TD-SCDMA SYSTEM

摘要

A method and apparatus for adjusting the power gain factors of code channels in a TD-SCDMA system are provided. The method includes the following steps: the number of transmission code channels in the uplink transmission sub-system is judged; the power gain factor of data part in each code channel is determined and standard multi-bit quantization is performed on it; the power gain factor of midamble part in each code channel is determined and standard multi-bit quantization is performed on it. The apparatus includes: a judging module, the first power gain factor determining module, the first quantization module, the second power gain factor determining module and the second quantization module. The invention resolves the difficulty in digital realization during specific hardware design caused by the value of power gain factor being decimal fraction and can be applied to specific hardware design and realization conveniently.
