Impulsive Noise Cancellation for MIMO Power Line Communications
Power line channels are often badly corrupted by impulsive noise. In this paper, an impulsive noise cancellation method for MIMO power line communication is proposed. First, the received signal is transformed into frequency domain and MIMO detection is carried out. Then, the detected signal is transformed back to time domain and the noise estimation can be obtained by subtracting detected signa...
متن کاملAdaptive-Filtering-Based Algorithm for Impulsive Noise Cancellation from ECG Signal
Suppression of noise and artifacts is a necessary step in biomedical data processing. Adaptive filtering is known as useful method to overcome this problem. Among various contaminants, there are some situations such as electrical activities of muscles contribute to impulsive noise. This paper deals with modeling real-life muscle noise with α-stable probability distribution and adaptive filterin...
متن کاملEfficient Algorithms for Noise Estimation in Electrical Power Line Communications
Power Line Communication (PLC) has received much attention due to the wide connectivity and availability of power lines. Effective PLC must overcome the harsh and noisy environments inherent in PLC channels. Noise in power lines is modeled as a cyclostationary Gaussian process. In order to achieve reliable communication using power lines, effective measures including error control techniques ne...
متن کاملHighly efficient signal processing for frequency agile power line communications
A modified frequency hopping signaling scheme has recently received a considerable attention by the designers of power line communication systems because of its insensitivity to frequencyselective and time-variant attenuation and high level of interference. In frequency hopping system, the increase of the data rate without increase of the hop rate is possible only if the receiver can detect all...
متن کاملAdaptive IIR Notch Filter Design For Cancellation of Periodic Impulsive Noise in OFDM Based Power Line Communications
This paper presents a simple and cost effective method to remove the periodic impulsive noise in power-line communications (PLC) system. In the real PLC environment, some electrical appliances will produce impulsive noise at a fixed frequency with the power spectral density (PSD) usually exceeding that of the received signals. This type of impulsive noise is the periodic impulsive noise, and it...
