Signal transmission and receiving method, system and apparatus based on filter bank

A signal receiving method based on a filter bank, comprising:

• determining, by an electronic device, whether post-equalization is to be performed to demodulated signals based on the filter bank according to pre-equalization configuration information, wherein the pre-equalization configuration information indicates whether pre-equalization is enabled or disabled;
• if the pre-equalization configuration information indicates that the pre-equalization is enabled, performing, by the electronic device, the post-equalization to the demodulated signals based on the filter bank according to a composite equivalent channel frequency response of pre-equalization coefficients and a channel frequency response;
• and
• if the pre-equalization configuration information indicates that the pre-equalization is disabled, performing, by the electronic device, amplitude and phase post-equalization to the demodulated signals based on the filter bank according to an estimated channel frequency response.

An electronic device for transmitting a signal based on a filter bank, comprising:

• a non-transitory computer-readable medium;
• and
• a processor, when executing instructions stored in the non-transitory computer-readable medium, configured to:
• receive a scheduling control signaling including a pre-equalization configuration information indicating whether pre-equalization is enabled, from a network,
• obtain pre-equalization configuration information from the scheduling control signaling,
• if the pre-equalization configuration information indicates that pre-equalization is enabled, generate pre-equalization coefficients, perform pre-equalization operation to transmission signals according to the pre-equalization coefficients, and perform modulation based on the filter bank;
• and
• if the pre-equalization configuration information indicates that the pre-equalization is disabled, perform modulation to the transmission signals without the pre-equalization based on the filter bank.
