Embodiment approach

[0067] In the baseband processing fixed-point system, the bit width occupied by the frequency domain data is the effective bit width of the frequency domain data, and the effective bit width will affect the accuracy of the baseband processing using the frequency domain data. Generally, the more effective bits, the higher the baseband processing accuracy, otherwise the lower the baseband processing accuracy. Therefore, within the maximum bit width limited by the processing system for frequency domain data, increasing the effective bit width of frequency domain data can improve the accuracy of baseband processing.

[0068] In the case where the channel to be baseband processed and other channels coexist on some symbols, if the transmit power of the channel to be baseband processed is small, the value of the frequency domain data to be baseband processed will also be small, That is, the effective bit width of the frequency-domain data to be baseband processed is relatively small,...

Embodiment approach 1

[0078] In the 5G downlink receiving system, when the transmission power of a certain channel on certain symbols is low, the effective bit width of the frequency domain data corresponding to this channel can be expanded according to this scheme, and the accuracy of subsequent baseband processing of this channel can be improved. Figure 4 is a schematic flowchart of a data processing method according to an optional embodiment of the present invention, such as Figure 4 As shown, the program includes:

[0079] In the first step, the time-domain data received by the receiving end is converted into frequency-domain data by operations such as de-CP and FFT.

[0080] The second step is to determine the channel to be processed. Taking the PBCH channel as an example, it can be deduced according to the protocol that when there is downlink service, the symbol carrying the PBCH channel may also carry the PDSCH channel, and the received power of the PBCH channel is lower than that of the ...

Embodiment approach 2

[0086] In the FDM ON scenario of the 5G downlink PDCCH channel, the transmission power of multiple channels on one symbol may be inconsistent, and this method can also be applied. According to the 5G protocol, in the FDM ON scenario, some symbols that carry the PDCCH channel also carry the PDSCH channel. At the same time, the transmission power of the PDSCH channel is relatively large, while the transmission power of the PDCCH channel is relatively small. Therefore, the bit width of the frequency domain data corresponding to the PDCCH channel is small, and directly inputting it into the subsequent baseband processing will affect the accuracy of the final result. Therefore, the frequency domain data can be processed according to the above steps.

[0087] In the first step, the time-domain data is converted through operations such as FFT to obtain frequency-domain data. In the second step, all frequency domain data of the PDCCH channel is fetched according to the protocol.

Abstract

The invention provides a data processing method and device, a storage medium and electronic equipment, and the data processing method comprises the steps: obtaining frequency domain data of a specified channel; adjusting the effective bit width occupied by the frequency domain data, wherein the effective bit width occupied by the adjusted frequency domain data is larger than the effective bit width occupied by the frequency domain data before adjustment; According to the frequency domain data base band processing method and device, the effective bit width of the frequency domain data is improved, and therefore the problem that the frequency domain data base band processing precision is low can be solved, and the effect of improving the frequency domain data base band processing precision is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data processing method and device, storage medium and electronic equipment. Background technique [0002] Different channels carry different information in a communication system. In order to reduce interference as much as possible and reduce transmission power under the premise of ensuring communication quality, each channel will perform power allocation during transmission processing. This will cause the transmission power of different channels to be different. Some channels have high transmission power, while others have low transmission power. The size of the transmit power will ultimately affect the actual data received by the receiver. [0003] As mentioned above, the transmission power of different channels will be different due to the power allocation. This will cause multiple channels with different transmission powers to exist simultaneously on some symbols in t...
