摘要： Techniques for performing IFFT pipelining are described. In some aspects, the pipelining is achieved with a processing system having a memory having first and second sections, an encoder configured to process data in each of the first and second memory sections, an IFFT configured to process the encoded data in the first and second memory sections, and a post-processor configured to process the IFFT processed data in the first memory section while the IFFT is processing the encoded data in the second memory section, the post processor configured to operate at a different clock speed than the encoder or the IFFT.

摘要： Techniques for performing IFFT pipelining are described. In some aspects, the pipelining is achieved with a processing system having a memory with a first, second and third sections, an encoder configured to process data in each of the first, second and third memory sections in a round robin fashion, an IFFT configured to process the encoded data in each of the first, second, and third sections in a round robin fashion, and a post-processor configured to process the IFFT processed data in each of the first, second and third memory sections in a round robin fashion.

摘要翻译： 描述了执行IFFT流水线的技术。 在一些方面中，流水线处理是利用具有带第一，第二和第三部分的存储器的处理系统来实现的，编码器被配置为以循环方式处理第一，第二和第三存储器部分中的每一个中的数据，配置IFFT 以循环方式处理第一，第二和第三部分中的每个部分中的编码数据;以及后处理器，被配置为以循环方式处理第一，第二和第三存储器部分中的每一个中的IFFT处理后的数据 。
