Abstract

The invention relates to a channel estimation method and apparatus, a wireless receiving device and a storage medium. The channel estimation method comprises the following steps of receiving communication sub-frames borne on sub-carriers in a communication link; acquiring a Doppler frequency offset of the communication link; determining a channel estimation strategy according to a frequency offsetthreshold value and the Doppler frequency offset; and according to the communication sub-frames borne on the sub-carriers and the channel estimation strategy, performing calculation to obtain channelestimation values of data symbols in the communication sub-frames. According to a value relation between the Doppler frequency offset and the frequency offset threshold value, the optimal channel estimation strategy is adaptively matched, so that on the basis that the demodulation performance of a system is ensured, the algorithm complexity of the channel estimation strategy is reduced.

Description

technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a channel estimation method, device, wireless receiving equipment and storage medium. Background technique [0002] Channel estimation refers to the process in which the receiving end of wireless communication estimates the model parameters of an assumed channel model from the received data. The more accurate the channel estimation value obtained by channel estimation, the more accurate the signal demodulation of the physical layer at the receiving end will be. Therefore, channel estimation is a key technique in wireless communication systems. [0003] There are many methods for channel estimation. In existing wireless communication systems, the channel estimation method based on pilot symbols is mainly used for channel estimation. Pilot symbols are set at two preset positions in the communication subframe, and two reference pilot symbols are stored at t...
