Estudo de códigos LDPC em sistemas OFDM com modulações 16-APSK sobre canal Rayleigh
(Universidade Federal de Santa MariaBRCiência da ComputaçãoUFSMPrograma de Pós-Graduação em Informática, 2014-03-17)
In this master s thesis, a wireless communication scheme with a single transmit and single
receive antenna, SISO case, with use of the OFDM multicarrier technique and application
of LDPC coding was considered. It is well ...
Análisis de las codificaciones de canal: LDPC y Turbo código, utilizando modulaciones no uniformes sobre canales AWGN con desvanecimiento.
(Escuela Superior Politécnica de Chimborazo, 2021-11-24)
This research it presents an analysis of LDPC and Turbo channel codes, using digital modulations with non-uniform NUC-QAM constellations of order M=64, 256, 1024 and 4096, in channels with additive white Gaussian noise ...
Performance of a Simplified Soft-Distance decoding algorithm for LDPC codes over the Rayleigh fading channel
(Planta Piloto de Ingeniería Química, 2013-07)
In this paper, we investigate the performance of a Soft-Input soft-Output decoding algorithm for LDPC codes that uses Euclidean distance as its metric, in the Rayleigh fading channel. It is found that its Bit Error Rate ...
