Method and its device for realizing multiple speed rate and code change

Abstract

This invention discloses a method and device for realizing multi rate adaptation and code pattern change, which contains plurality of parallel connected code pattern change process unit with different process mode, rate mode detecting unit for unlink channel data stream, and resource distribution unit. Said invention distributes resource in arithmetic unit pool to code pattern process unit after determining transmission mode of said channel data stream according to detection result, to complete code change. Compared with current technology, said invention has low cost and raised operation versatility.

Description

technical field [0001] The present invention relates to a method and device for realizing multiple (two or more) rate adaptation and code pattern conversion, and in particular to rate adaptation and code pattern for digital signals transmitted in wireless telecommunication networks and wireless networks Transformation method and device thereof. Background technique [0002] With the development of communication technology today, on the premise of ensuring communication quality, how to improve spectrum efficiency is our most concerned issue. In wireless communication technology, such as GSM network, this point is reflected more obviously. [0003] At present, in a mobile communication system based on the GSM standard, more than two transmission modes of transmission rate and code conversion are provided. Specifically, the full rate mode (FR) and the enhanced full rate mode (EFR) are defined in the protocol GSM08.60, in which the digital voice service or data service signal ...

AI Technical Summary

Problems solved by technology

In this way, for each transmission mode, it is necessary to redesign an independent circuit board to realize rate adaptation and code conversion, and the upgrade ability is very poor.

[0007] Secondly, at different times or in different places, the use of transmission modes in the communication network is very complicated. Since each circuit board can only handle a single transmission mode, and this processing capacity is also limited, therefore, in this Under this scheme, it is very difficult to dynamically meet the support for different usage quantities of various transmission rates, and it may be necessary to continuously add or replace circuit boards to achieve this, which is very rigid and inflexible

[0008] Finally, the circuit boards corresponding to each rate have implemented rate adaptation and code conversion functions, and there is almost no difference in the specific circuit implementation of these circuit boards. In this way, a single board is provided independently for each transmission mode cost input, resulting in great waste
