Problems solved by technology

However, in PCE2, the corresponding relationship between the different symbol rates in the original EGPRS2 and its coding methods and modulation methods is still used. For the sending end, different sending rates correspond to different numbers of symbols, and processing symbols of different lengths will introduce IDFT modules of different lengths, and other processing processes of different burst structures will increase the complexity of implementation at this time; and for the receiving end, there are many combinations of modulation methods and rates (such as figure 1 6 types are shown), which requires more types of discrimination at the same time, which also leads to a large and complicated detection process of the identification code

Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] In the PCE2 technology, the processing of the original time-domain signal is transformed into the frequency domain, so that the improvement of the modulation order greatly reduces the impact on the demodulation complexity and performance, thus bringing greater flexibility to the design of coding and modulation. Currently, there are 16 channel coding methods in the PCE2 technology, and each channel coding method corresponds to a modulation m...

Abstract

The embodiment of the invention provides a data processing method and equipment. For a transmitting end, the data processing method comprises the following steps of obtaining data to be processed and a channel coding mode of the data to be processed; determining a modulation mode of the data to be processed in accordance with the channel coding mode and the preestablished corresponding relation between the channel coding mode and the modulation mode; coding the data to be processed in accordance with the channel coding mode, and modulating the data to be processed in accordance with the established modulation mode; and sending processing results in accordance with a fixed symbol rate after the data to be processed is coded and modulated. By using the scheme provided by the invention, the complexity of processing the data at the transmitting end can be effectively reduced. Additionally, the detection quantity of identifying the coding process at a receiving end is reduced, and the complexity is reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a data processing method and equipment. Background technique [0002] In EGPRS2 (Enhanced GPRS phase 2, Enhanced General Packet Radio Service Phase 2), Level-A and Level-B services will be sent at different symbol rates, where Level-A uses NSR (Normal Symbol Rate, common symbol Rate), specifically 270.833kbps, Level-B uses HSR (Higher Symbol Rate, high symbol rate), specifically 325kbps, where HSR is 1.2 times that of NSR. [0003] In EGPRS2, the channel coding method has a corresponding relationship with the modulation method and rate. In the process of data processing, the sending end selects the channel coding method to encode the data to be processed according to the current channel conditions, and selects the modulation method in the corresponding relationship to modulate the encoded data, and then sends it to the receiving end at a corresponding rate. Aft...
