Abstract

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine indices associated with m consecutive elements. In an aspect, each of the m consecutive elements may be associated with a different index. In addition, the apparatus may bit reverse a binary sequence associated with each of the m consecutive elements. In an aspect, eachof the m consecutive elements may include a different binary sequence. Further, the apparatus may determine a bit-reversed order of the indices based at least in part on the bit-reversed binary sequence associated with each of the m elements. In addition, the apparatus may write each of the m consecutive elements to a different memory bank in parallel based at least in part on the bit-reversed order of the indices.

Description

[0001] Cross references to related applications [0002] This application requires the U.S. Provisional Application Serial No. 62 / 444,261 filed on January 9, 2017 named "LOW LATENCY BIT-REVERSED POLARCODES" and the name "LOWLATENCY BIT-REVERSED" filed on September 14, 2017 For the rights and interests of US Patent Application No. 15 / 704,204 of "POLLAR CODES", the disclosures of the above applications are expressly incorporated herein by reference. Technical field [0003] The present disclosure relates generally to communication systems, and more specifically to performing semi-parallel and / or parallel bit reversal at a polar encoder and / or polar decoder. Background technique [0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may adopt multiple access technologies that can support communication with multiple users by sharing ava...
