Recently, proportionate adaptive filters are commonly used in the acoustic echo cancellation problems. In proportionate adaptive filters, for each coefficient a step-size which proportional to magnitude of that coefficient is applied. Hence, adaptive filter converges more rapidly to its steady state. Developed proportionate method were applied to algorithms which are robust against impulsive noise. Consequently, algorithms which converge quickly and robust against impulsive noise are obtained for acoustic channels. In this paper, we proposed Gradient Controlled Improved Proportionate Affine Projection Sign Algorithm, which is obtained by modifying Gradient Controlled Improved Proportionate Affine Projection Algorithm such that it will work for acoustic channel with impulsive noise. According to the simulation results, proposed algorithm has better performance than the algorithms in the literature in terms of convergence speed.

A New Method For Efficient Bandwidth Control of Narrowband Planar Filters
Alicioglu, Bulent; Boyacioglu, Gokhan; Oruc, Sacid; Yavuz, Caglar; Yıldırım, Nevzat (2013-10-10)
Narrowband filters that are utilized in the IF stages are almost the most effective components when the performance parameters such as the Intermodulation Spurs (IMS) and noise floor of the entire strip are considered. Thus, selectivity of the IF filters should be as high as possible. Required sharpness and ultimate rejection often dictate high Q-structures like cavity or waveguide structures, but these type of filters fail to comply with physical parameters such as space and weight that planar filters do. ...
Synthesis Approach for Compact Ku-Band Waveguide Lowpass Filters with Wide Rejection Bandwidth
Cetin, Metehan; Boyacioglu, Gokhan; Alicioglu, Bulent; Yıldırım, Nevzat (2018-11-02)
Classical corrugated waveguide (WG) LP filters with wide rejection bandwidths rely on designing a band stop block with reduced height waveguides augmented by impedance matching blocks at terminations. In this paper direct synthesis approach is used to synthesize the whole filter as a single unit. The initial filter is designed as a TEM mode commensurate length LPF with very high quarter wavelength frequency for size reduction. Filter is made up of series SC stubs interlaced by contributing Unit Elements (UE...
Prediction of Vibro-Acoustic Response of Enclosed Spaces by Using Structural Modification Techniques
Demirkan, O.; BAŞDOĞAN, FATMA İPEK; Özgüven, Hasan Nevzat; Çalışkan, Mehmet (2010-09-22)
Low frequency noise caused by vibrating panels can become a problem for vehicles from NVH standpoint. The vibro-acoustic analysis of a simplified vehicle model is presented in this study. Analysis of vibro-acoustic behavior includes frequency response analysis of structure by Finite Element Method (FEM) and sound pressure level (SPL) prediction of the cabin interior by Boundary Element Method (BEM). The structural design of the vibrating panels can be modified by adding stiffeners to improve the acoustic fi...
LINE INTERFERENCE SUBTRACTION FILTER FOR SIGNAL-AVERAGED ELECTROCARDIOGRAPHY
IDER, YZ; SAKI, MC (1993-09-08)
Use of notch filters in signal averaged ECG applications is avoided because they introduce ringing following the QRS. The authors therefore studied the use of a line interference subtraction (LIS) filter by which a scaled and shifted version of a signal at line frequency (line reference signal, LRS) is subtracted from the ECG signal in order to reduce the level of line interference. The frequency of the LRS must be the same as that of the line interference. For this, hardware is developed such that line fre...
