One of the major factors of performance degradation in OFDM systems is influence of additive impulsive noise. Especially, reception characteristic is extremely degraded under multi-path channel. Many efficient impulsive noise reduction schemes are proposed for low order modulation such as QPSK, 16QAM. However, in higher order modulation as 64QAM, reception(More)
In order to improve performance of high-speed power line communication (PLC) using OFDM (Orthogonal Frequency Division Multiplexing), compensation of the influence of additive impulsive noise is required. In this paper, the scheme to make precise channel estimation under impulsive power line channel is proposed. Although many schemes to improve influence of(More)
OFDM (Orthogonal Frequency Division Multiplexing) is used in many applications that require high-speed communication. However, in the system using OFDM such as PLC (power line communication), there is a problem that reception characteristics are strongly deteriorated by the impulsive noise because impulsive noise has short time duration and very large(More)
