TD-SCDMA系统中时/频/相偏在定点DSP中的实现
首发时间:2010-12-03
摘要:时偏、频偏与相偏的理论研究已经很成熟,但在实际工程应用中,要根据需求考虑实现的复杂度、成本、灵活性以及可兼容性等因素,选择一个最优方案来实现相应功能。本文通过对比各实现方案,选择了最优方案在定点DSP中实现了TD-SCDMA系统中要求的时偏、频偏与相偏。

The implementation of time/frequency/phase offset in TD-SCDMA in fixed-point DSP
Abstract:The theory of time offset, frequency offset and phase offset is mature, but in practical application, according to the needs to consider implementation complexity, cost, flexibility, and compatibility and other factors, choose an optimal program to achieve the corresponding function. This paper compares the various implementations to select the best program in the fixed-point DSP to implement the requirements of the timing offset, frequency offset and phase offset in TD-SCDMA system.
Keywords: TD-SCDMA Time offset Frequency offset Phase offset Fixed-point DSP
