Abstract
The present disclosure relates to a method for transmitting or receiving a signal by a reception device in a wireless communication system, and the method may comprise the steps of: receiving, from a transmission device, a signal modulated on the basis of a differential phase shift keying (DPSK) scheme; converting the received signal into an input signal of a spiking neural network (SNN); calculating an output value through the spiking neural network previously learned; and converting the output value into an input signal of a channel decoder.
Claims11
A method of a receiving device to receive signals in a wireless communication system, the method comprising:
- receiving a signal modulated based on a differential phase shift keying (DPSK) scheme, from a transmitter;
- converting the received signal into a first input signal of a spike neural network (SNN);
- obtaining an output value through the SNN;
- converting the output value into a second input signal of a channel decoder;
- and
- providing the second input signal to the channel decoder, and
- wherein the received signal is converted into the first input signal of the SNN based on at least one of a spike rate, a spike timing, or a spike sequence, and
- wherein based on the received signal being converted based on the spike timing, a log-likelihood ratio (LLR) value is obtained from the output value based on a time difference between the output value and a time label and is converted into the second input signal of the channel decoder.
A device of receiving signals in a wireless communication system, the device comprising:
- a receiver;
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
- receiving a signal modulated based on a differential phase shift keying (DPSK) scheme, from a transmitter;
- converting the received signal into a first input signal of a spike neural network (SNN);
- obtaining an output value through the SNN;
- converting the output value into a second input signal of a channel decoder;
- and
- providing the second input signal to the channel decoder, and
- wherein the received signal is converted into the first input signal of the SNN based on at least one of a spike rate, spike timing, or a spike sequence, and
- wherein based on the received signal being converted based on the spike timing, a log-likelihood ratio (LLR) value is obtained from the output value based on a time difference between the output value and a time label and is converted into the second input signal of the channel decoder.
