Abstract
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system for supporting higher data rates Beyond 4th-Generation (4G) communication systems such as Long Term Evolution (LTE). A method for operating a receiver in a wireless communication system may include: receiving a signal from a transmitter; performing Integer Forcing (IF) equalization on the received signal; determining a log LikeLihood Ratio (LLR) value of each bit by using a posteriori probability of each bit for the signal determined based on an equalization matrix and a likelihood value for the signal; and decoding the signal by using the LLR value.
Claims18
A method for operating a receiver in a wireless communication system, the method comprising:
- receiving a signal from a transmitter;
- performing integer forcing (IF) equalization on the received signal;
- determining a log likelihood ratio (LLR) value of each bit by using a posteriori probability of each bit for the signal that is determined based on an equalization matrix and a likelihood value for the signal;
- and
- decoding the signal by using the LLR value.
A receiver in a wireless communication system, the receiver comprising:
- a transceiver;
- and
- at least one processor operatively coupled with the transceiver,
- wherein the at least one processor is configured to control to:
- receive a signal from a transmitter, and
- perform integer forcing (IF) equalization on the received signal, determine a log likelihood ratio (LLR) value of each bit by using a posteriori probability of each bit for the signal that is determined based on an equalization matrix and a likelihood value for the signal, and decode the signal by using the LLR value.
A transmitter in a wireless communication system, the transmitter comprising:
- a transceiver;
- and
- at least one processor operatively coupled with the transceiver,
- wherein the at least one processor is configured to control to:
- determine a codeword corresponding to bits input into the transmitter, perform binary modulation on the respective bits of the codeword, and combine binary-modulated symbols generated based on the binary-modulated bits, and
- transmit the combined binary-modulated symbols to a receiver.
