本文介绍了一种基于时域混叠抵消（TDAC）[1]，[2]的奇异堆叠、临界采样、单边带（SSB）[7]分析/合成系统。开发了分析和综合滤波器响应的规范，并描述了一些满足重建要求的设计。讨论了TDAC系统在子带/变换编码中的应用，给出了采用几种不同窗口设计的32带编码器的客观性能，并与基于频域混叠抵消（FDAC）滤波器组[3]-[5]的编码器进行了比较。
A new, oddly stacked, critically sampled, single side-band (SSB) [7] analysis/synthesis system based on Time Domain Aliasing Cancellation (TDAC) [1],[2] is described in this paper. The specifications for the analysis and synthesis filter responses are developed and a number of designs which satisfy the reconstruction requirements are described. The application of TDAC systems to Subband/Transform coding is also discussed and the objective performance of a 32 band coder using several different window designs is presented and compared with a coder based on Frequency Domain Aliasing Cancellation (FDAC) filter banks [3]-[5].
