Embodiment Construction

[0023] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0024] First, please refer to figure 1 , which shows a structural block diagram of the extended system of the bit interleaving memory of the present invention. As shown in the figure, the extended system of the present invention includes a first address mapping module 12 and a second address mapping module 14 . The first address mapping module 12 performs swap mapping of the row and column addresses based on the row and column addresses of the memory once bit-interleaved, and superimposes and expands the swap mapping addresses and the r...

Abstract

The invention relates to a method for expanding bit interleaving memories, comprising the following steps of: interchanging and mapping address files of memories based on primary bit interleaving; overlying the interchanged and mapped addresses and the address files of the memories to obtain first mapping addresses; evenly mapping the first mapping addresses to a plurality of memories and mappingthe plurality of memories as memories simultaneously executing bit interleaving and read-write operation. The invention can utilize the memories with smaller memory space to interleave data.

Description

technical field [0001] The present invention relates to communication technology, in particular to an expansion system and method of a bit interleaving memory. Background technique [0002] In mobile communications, in order to further improve the anti-jamming performance of data transmission, the interleaver is often used to scramble the original data sequence, so that the correlation of the data sequence before and after interleaving is weakened, which greatly reduces the impact of data burst errors. For example, regular interleaving typically takes data in rows and outputs it in columns. [0003] In some digital communication protocols, although the bit interleaver only interleaves the data stream, it has a large capacity and complex timing. Due to its own functional decision, the data can only be read out when it is almost fully charged. For example, data can only be read out by column after the input data by row fills the entire interleaver. Therefore, according to t...
