基于滤波器组的多路复用转换系统与现有的基于DFT的多载波系统相比具有一定的优势，是频率选择性信道中数据传输的理想选择。我们最近提出了一种新的和有效的信道均衡的想法，用于临界抽取完美重构余弦调制复用转换系统。该均衡器在接收端采用并行的余弦和正弦调制滤波器组。本文探讨了所需的并行滤波器组系统的有效实现结构，这也发现在其他领域的应用。
Filter bank-based transmultiplexer systems have certain advantages compared with existing DFT-based multicarrier systems and they are promising candidates for data transmission in frequency-selective channels. We have recently proposed a novel and efficient channel equalization idea to be used with critically decimated perfect reconstruction cosine modulated transmultiplexer systems. The equalizer utilizes parallel cosine and sine modulated filter banks in the receiver end. This paper explores efficient realization structures for the needed parallel filter bank system, which finds applications also in other areas.
