Frequency response masking (FRM) technique along with the Canonic Signed Digit (CSD) representation is a good alternative for the design of a computationally efficient, sharp transition width, high speed finite impulse response (FIR) filter. This paper proposes two novel approaches for the joint optimization of an FRM FIR digital filter in the CSD space.(More)
In this paper, we present a novel and efficient method for the design of a sharp, two dimensional (2D) wideband, circularly symmetric, FIR filter. First of all, a sharp one dimensional (1D) infinite precision FIR filter is designed using the Frequency Response Masking (FRM) technique. This filter is converted into a multiplier-less filter by representing it(More)
Ever since the pioneering work of Y.C. Lim[1] on frequency response masking for the design of sharp FIR filters, lot of significant research have been carried out in this area. Among the various Signed Power of Two(SPT) forms, the Canonic Signed Digit(CSD) is a minimal representation, since it represents a given multiplier coefficient using minimum number(More)
Remote authentication is the most commonly used method to determine the identity of a remote client. Secure and efficient authentication scheme has been a very important issue with the development of networking technologies. In a Generic Framework for Authentication, preserving security and privacy in distributed systems provide three factors for(More)
