Decoding Performance Analysis and DSP Optimization for Block Turbo Code
摘要
Abstract
Based on the classic decoding algorithm of Block Turbo Code(BTC), the relationship between decoding parameters and decoding complexity, and the impact of different parameters on performance, are analyzed. Taking a kind of (15, 1 l)x(13, 9) BTC for example, the software implementation scheme on C55 series Digital Signal Processor(DSP) is presented considering the compromise between performance and complexity. The optimization is done through different levels such as fix-point processing, compiler options, high-level language and assembly language. Computational complexity has 89% reduction after optimization.关键词
