Embodiment Construction

[0058] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the preferred embodiments are specifically cited below, and in conjunction with the accompanying drawings, the detailed description is as follows:

[0059] figure 1 An exemplary system is schematically illustrated according to an embodiment of the disclosure. System 100 may be part of a wireless communication system, eg, a coded OFDM communication system at the transmitter. System 100 may include an input interface 105 configured to receive an input of a data stream, which may include at least one sequence of data having, for example, encoded data bits. System 100 may include encoding device 110 configured to perform encoding, such as speed-up encoding and / or permutation of a data stream. In one embodiment, the encoding device 110 may include a channel encoder 115 , a bit-to-symbol mapper 120 , and a resource allocation device 125 . Channel...

Abstract

A wireless communication method implemented in a communication system includes receiving a first data sequence, and processing the first data sequence to obtain information containing at least one of a first number and a sampling spacing associated with the first data sequence. The method also includes permuting the first data sequence to generate a permuted second data sequence. Permuting the first data sequence includes determining a first parameter based on at least one of the first number and the sampling spacing, determining a second parameter based on at least one of the first parameter, the first number, and the sampling spacing, and determining a mapping relationship between a j-th data item of the permuted second data sequence and an i-th data item of the first data sequence. The method further includes outputting the permuted second data sequence.

Description

technical field [0001] The present invention relates to a communication method and system, in particular to a wireless communication method and system with an arrangement structure. Background technique [0002] In current communication systems, signals may be transmitted from a source location to a destination location in either analog or digital form. For example, the use of digital data communication may increase the capacity of data transmission, the flexibility of data operations, and so on. Signals containing data such as those derived from test, image, sound, video, etc. may be encoded into a sequence of symbols or binary symbols, and then received over-the-air from the transmitter via one or more communication channels, such as via cable or transmission sent to the receiver. [0003] In digital communication systems, data can be transmitted over one or more frequency bands within a limited bandwidth. When multiple channels are used, these channels may overlap each...
