Definitions
- the power allocation will cause differences in the transmit power of different channels. This will cause multiple channels with different transmit powers to exist on certain symbols at the same time in the transmission bandwidth.
- the time-domain data of these symbols is converted into frequency-domain data through FFT, the data of the entire symbol may be converted together, so in the case of the same calibration, the frequency domain data of the channel with high transmission power on the same symbol The value is larger, and the smaller the value corresponding to the smaller transmit power.
- the frequency domain data with a large value has a large effective bit width, while a small value has a small effective bit width. Since the processing accuracy of different bit widths is different, if the frequency domain data with a smaller effective bit width is directly input to Subsequent baseband processing will affect the accuracy of the final processing result of this channel.
- the bit width difference between the sub-storage space and the sub-frequency domain data refers to the bit width of the sub-storage space storing the sub-frequency domain data (for example, it may be pre-defined The difference between the set maximum bit width for storing sub-frequency domain data and the bit width of the sub-frequency domain data.
- each of the above modules can be implemented by software or hardware.
- it can be implemented in the following manner, but not limited to this: the above modules are all located in the same processor; or, the above modules can be combined in any combination.
- the forms are located in different processors.
- the third step is to calculate the bit widths occupied by the real and imaginary parts of the frequency domain data taken out for each symbol. And find a maximum value N among all the bit widths. Subtract the value of M from the value of N to get the value of S, which is the number of bits to be shifted in the frequency domain data of this symbol.
- the third step is to calculate the effective bit width of the real and imaginary parts of all frequency domain data for a single symbol.
- the fifth step is to input the shifted frequency domain data into the subsequent processing.
- the subsequent processing algorithm determine whether to restore the left shift number.
- the effective bit width occupied by the frequency domain data is adjusted, wherein the effective bit width occupied by the frequency domain data after adjustment is higher than that before adjustment.
- the effective bit width occupied by the frequency domain data; baseband processing is performed according to the adjusted frequency domain data, which increases the effective bit width of the frequency domain data.
- the greater the effective bit width of the frequency domain data the baseband processing accuracy The higher is, therefore, the problem of low frequency-domain data baseband processing accuracy can be solved, and the effect of improving the frequency-domain data baseband processing accuracy can be achieved.
