The main characteristics of any wireless communication system are deteriorated as a result 12 of the effect of the additive and multiplicative noise. The effect of addition of noise and 13 interference to the signal generates an appearance of false information in the case of the 14 additive noise. For this reason, the parameters of the received signal, which is an additive 15 mixture of the sig...

The scope of this paper is interference cancellation which is concerned with removal of noise superposed on speech signal. Interference cancelling makes use of an auxiliary or reference input derived from one or more sensor located in noise field where the signal is undetectable. This input is filtered from primary input containing both signal and interference. Adaptive filtering which are able...

This paper proposes an interference suppression technique using edge-removal filter in the transmitter, as well as, nulling filter and turbo equalizer in the receiver for carrier interferometry (CI) based one-cell reuse single-carrier time division multiple access (TDMA) systems. In the proposed system, the desired signals in the reference cell are interfered by interference including adjacent-...

For a GNSS receiver’s robustness against RFI and the high accuracy of navigation solution in GNSS, interference source detection and mitigation are needed. In this paper, an adaptive lattice IIR notch filter is employed to track single-tone continuous wave and swept continuous wave interference signals, and an interference detection method is proposed. Furthermore, this paper presents interfere...

In this paper, we derive an expression for the signal to interference-plus-noise ratio of a linear multistage parallel interference cancellation receiver. We focus on a linear multistage receiver which converges to the linear minimum mean-squared error receiver as the number of stages increases. The signal to interference-plus-noise ratio is given in terms of the system loading, the partial can...

This paper treats the problem of digital TV terrestrial broadcasting in presence of co-channel interference from analogue TV services. The channel capacity is calculated for the optimum distribution of the transmitted power. An OFDM scheme is presented which is designed to be robust to the analogue TV interference. Power and number of bits per symbol are assigned to each OFDM channel to give th...

An ECG signal is basically an index of the functionality of the heart. For example, a physician can detect arrhythmia by studying abnormalities in the ECG signal. Since very fine features present in an ECG signal may convey important information, it is important to have the signal as clean as possible. Power line interference may be significant in electrocardiography. Often, a proper recording ...

In this paper, wireless mobile communication system in the presence of short term fading, long term fading and co-channel interference subjected to short term fading is considered. Desired signal experiences Nakagami-m short term fading and Gamma long term fading, and co-channel interference experiences Nakagami-m short term fading. In interference limited wireless fading channel, the ratio of ...

During the last decade, an adaptive antenna has considerable received the interest for mobile communication systems. This is because it can increase the system capacity by reducing interference. To achieve the interference reduction, an adaptive algorithm is necessary. There are a number of the adaptive algorithms proposed to improve the signal-to-interference plus noise ratio (SINR) in such th...
