Problems solved by technology

[0003] Since the WiMAX system supports up to 17 kinds of packet lengths, and the maximum packet length is 2400 bit pairs (bit pair), if storing all interleaved addresses, 100Kbit of storage space is required, so the storage resources are relatively large, and it is necessary to search according to the packet length Different tables, the implementation method is more complicated

Abstract

The invention discloses a method and system for parallel computing of an interweaved address. The method comprises the steps of: pre-configuring and storing an interweaved address compress table; receiving data to be decoded and judging decoding parallelism; reading the interweaved address compress table according to the length of a packet of the data to be decoded, so as to acquire a value P0 and an interweaving computing intermediate value; and generating the interweaved address and a reading address according to the decoding parallelism, the length of the packet of the data to be decoded, the value P0 and the interweaving computing intermediate value, and reading the data to be decoded according to the reading address so as to complete interweaving operation. According to the technical scheme in the invention, the parallel computing of the interweaved address inside a decoder in a WiMAX (Worldwide Interoperability for Microwave Access) system can be realized.

Description

technical field [0001] The invention relates to a Worldwide Interoperability for Microwave Access (WiMAX, Worldwide Interoperability for Microwave Access) system in the communication field, in particular to a parallel computing method and system for interleaving addresses. Background technique [0002] In order to resist burst errors in the transmission process, interleaving technology is used in the encoder in the WiMAX system, and the calculation of the interleaving address / deinterleaving address needs to be completed when the receiving end performs decoding. Because the calculation of the interleaved address is relatively complicated, in order to achieve a higher decoding throughput rate, a parallel mode is used to complete the decoding during the decoding process. The use of parallel decoding refers to the use of segmented storage, that is, the data sequence is divided into K segments (K is the decoding parallelism), and stored in the K piece of data buffer, which is the...
