Background and Aim: Exposure to impact noise (short-term, high intensity) higher than permitted levels results in injury to the auditory system. Armed forces are one of the occupational groups exposed to these types of noises resulting from gunshots. In this study, relevant articles and research on the adverse effects of impact noise, hearing loss, and tinnitus in armed forces and effective con...

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...

This paper presents an active noise cancellation technique for recovering wearable biosensor signals corrupted by bodily motion. A finger mounted photoplethysmograph (PPG) ring sensor with a collocated MEMS accelerometer is considered. The system by which finger acceleration disturbs PPG output is identified and a means of modeling this relationship is prescribed using either FIR or Laguerre mo...

Here we present a Continuous Wave radar receiver with a digital noise cancellation circuit. The leakage signal is cancelled by the mixer/PLL followed by an analog low pass filter also works as anti aliasing filter for the Ato-D. The digital signal processing after A-to-D cancels the analog thermal noise from front end which is mathematically AWGN in nature. We assume synchronous CDMA transmissi...

We report on the realization of delivering coherent optical frequency to multiple places based passive phase noise cancellation over a bus topology fiber network. This technique mitigates any active servo controller main link and at arbitrary access as opposed conventional technique, in which an compensation circuit has be adopted stabilize link. Although residual power spectral density propose...

In this paper, interference mitigation capabilities of a noise-based wireless modulation technique are considered. In particular, the effect of narrowband interferers on the BER performance of such a system that uses pure noise as an information bearer is analyzed. The main scope of this paper is to compare the performance analysis of the various interference cancellation schemes for the noise ...

This paper investigates the effects of phase noise on the performance of Polynomial Cancellation Coded Orthogonal Frequency Division Multiplexing (PCCOFDM). Phase noise will cause two effects on PCCOFDM, one is a Common Phase Error (CPE) and the other is Interchannel Interference (ICI). CPE is constant for all subcarriers in a symbol so that it can be corrected using existing techniques while t...

Wideband active noise control systems usually have hundreds of taps for control filters and the cancellation path models, which results in high computational complexity and low convergence speed. Several active noise control algorithms based on subband adaptive filtering have been developed to reduce the computational complexity and to increase the convergence speed. The subband structure is si...
