—An integrated system for code-division multiple access (CDMA) radio access to asynchronous transfer mode (ATM) network is considered. The inherently high error rate associated with the Rayleigh fading channel is overcome by two-dimensional CRC codes for efficient ATM–CDMA interfacing. Simulations show promising error probability performance with low coding(More)
—In this paper, a new FIR adaptive filtering algorithm is introduced. This algorithm is based on the Quasi-Newton (QN) optimization algorithm. The approach uses a variable step-size in the coefficient update equation that leads to an improved performance. The simulation results show that the algorithm has very similar performance to the Robust Recursive(More)
Ahstract-The recently proposed Recursive Inverse (RI) Adaptive Filtering algorithm uses a variable step-size and the first order recursive estimation of the correlation matrices in the coefficient update equation which lead to an improved performance. In this paper, a new FIR adaptive filtering algorithm is introduced. This algorithm uses the second order(More)
A novel adaptive FIR filter for the estimation of a single-tone sinusoid corrupted by additive noise is described. The filter is based on an offline optimization procedure which, for a given notch frequency, computes the filter coefficients such that the frequency response is unity at that frequency and a weighted noise gain is minimized. A set of such(More)
A new LMS algorithm is introduced for improved performance when a sinusoidal input signal is corrupted by correlated noise. The algorithm is based on shaping the frequency response of the transversal filter. This shaping is performed on-line by the inclusion of an additional term similar to the leakage factor in the adaptation equation of leaky LMS. This(More)
A novel offline-optimized adaptive filtering (OOAF) algorithm is proposed which allows the coupled estimation of waveform and frequency of a single-tone sinusoid in additive Gaussian noise. In a specified range of frequencies, the coefficients of a FIR filter are computed to minimize a given noise power. At a particular frequency in the range, quadratic(More)
