Abstract

Official abstract text for this publication.

A method for generating a decoding metric in a wireless communication system includes receiving an FQAM symbol and determining transmission probabilities of FQAM symbol candidates from a received value of the FQAM symbol, wherein the transmission probabilities of the FQAM symbol candidates are determined by multiplying a probability that a QAM symbol included in the FQAM symbol is mapped to each of candidate values in one frequency and a probability that a signal is not transmitted in the other at least one frequency. An apparatus in a wireless communication system for supporting FQAM, the apparatus comprising an RF processing unit configured to receive an FQAM symbol, and a modem configured to determine transmission probabilities of FQAM symbol candidates from a received value of the FQAM symbol.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for supporting Frequency Quadrature Amplitude Modulation (FQAM), the method comprising: receiving an FQAM symbol; and determining transmission probabilities of FQAM symbol candidates from the received FQAM symbol, wherein the transmission probabilities of the FQAM symbol candidates are determined by multiplying a probability that a Quadrature Amplitude Modulation (QAM) symbol included in the FQAM symbol is mapped to each of candidate values in o…
