The invention discloses a decoding method, device, electronic equipment and storage medium. The method includes: receiving frequency domain data, the frequency domain data includes pilot symbols and data symbols; performing channel estimation on the pilot symbols to obtain a channel response, and Filter the channel response to obtain the noise sequence; equalize the pilot symbols according to the channel response and the noise sequence to obtain the pilot equalization result, and obtain the data equalization result according to the channel response and the noise sequence equalization data symbols; determine according to the pilot equalization result and the reference pilot Pilot deviation, and calculate the deviation factor according to the pilot equalization result and the pilot deviation; determine the soft information according to the pilot deviation, deviation factor and data equalization result, and input the soft information into the decoder for decoding. In the embodiment of the present invention, deviation compensation is used to improve the accuracy of software information in the process of software information reconstruction, and the reliability of soft information is reflected by setting pilot frequency deviation instead of signal-to-noise ratio, thereby reducing the difficulty of decoding.
Description
technical field [0001] Embodiments of the present invention relate to wireless communication technologies, and in particular, to a decoding method, device, electronic equipment, and storage medium. Background technique [0002] In a wireless communication system, due to the time-varying nature of the channel, pilot symbols and data symbols are usually sent and received in series. To avoid loss of effective information, soft-decision decoding is used. First, the channel response and noise sequence are obtained by channel estimation based on the pilot symbols, and then the channel response and noise sequence are brought into the data symbols for equalization calculation to obtain the equalization result to calculate the channel signal. The corresponding soft information is decoded. It can be seen that the closeness between channel estimation and real channel response will affect the reliability of soft information. At present, the result of channel estimation is mainly obtai...
