Bias removal in a modified indirect plain gradient (MIPG) algorithm is presented in this paper. The proposed technique can remove the bias existing in the estimated parameter with little increasing of computation. In addition, steady state analysis of the convergence behavior and bias are derived in closed form. Computer simulations are conducted to(More)
The Phase/Amplitude shift keying modulator using digital oscillator is presented in this work. The proposed method comprises of digital line coder, digital differentiator and digital oscillator. The line coding signal is transformed into impulse signal to excite the oscillator to generate the desired PSK or ASK signal. The advantages of this technique are(More)
A simple and efficient method for canceling sinusoidal interference is presented in this paper. The interference of known frequency is modeled as a sum of unknown amplitude and zeros phase sine and cosine components. The amplitude of those components are sequentially estimated interms of Wiener-Hopf solutions using cumulative average system. Additionally,(More)
A modification of error function of a modified indirect plain gradient algorithm (MIPG) is presented in this paper. The objective is to improve the stability of the MIPG. In this modification, we have derived a new adaptive algorithm, namely, improved MIPG algorithm (IMIPG). The methodology of modifying is the sum of the two error functions. The former is(More)
The gradient algorithm used absolute value of error signal as a criterion to adjust the filter coefficient of adaptive IIR notch filter is presented in this paper. The objective is to estimate or track the frequency of a single sinusoidal signal corrupted by additive white Gaussian noise. The proposed algorithm can solve the problem of selecting an initial(More)
This paper presents an alternative method to generate the digital frequency modulation (FM) signal. By summing an information signal m(k) with the oscillating frequency &#x03C9;<inf>0</inf> and putting the result into the cosine function of digital oscillator coefficient which is &#x2212;2 cos (&#x03C9;<inf>0</inf> +m(k)), the FM signal is obtained.(More)
