A design methodology for low-power analog filters is reported. In order to reduce the power consumption, power optimization is included at three different levels of the filter design flow. First, an appropriate transfer function is selected fulfilling the required input-output relation specifications. Then, an orthonormal ladder filter structure is chosen as it offers the best filter topology c...

Abstract— One of the challenging issues for Filter Bank Multicarrier (FBMC) systems is their high Peak-to-Average Power Ratio (PAPR) which leads to the saturation of the high power amplifiers and consequently increases the out of band power. In this paper, we evaluate different FBMC PAPR reduction techniques and especially analyze the impact of the prototype filter length/overlapping factor on ...

The Finite Impulse Response (FIR) filters are widely used in many Digital Signal Processing (DSP) applications. For these applications, the low power, less area, high speed and low complexity FIR filter architectures are required. The researchers have proposed many FIR filters to meet the above design specifications. This paper is focused on the some efficient reconfigurable FIR filter architec...

This paper proposes a design of low power and low delay digital finite-impulse response (FIR) filter. Nowadays, there are many portable applications requiring low power and high throughput than ever before. Thus, low power system design has become a significant performance goal. The Finite Impulse Response (FIR) Filter is the important component for designing an efficient digital signal process...

CDMA systems are limited by the interference that users create for each other. Several methods of controlling and/or suppressing the interference through power control, multiuser detection (temporal filtering) and beamforming (spatial filtering) are studied to increase the capacity of CDMA systems [ 1-31. We investigate the capacity increase that is possible by combining power control with inte...

In embedded processors, instruction fetch and decode can consume more than 40% of processor power. An instruction filter cache can be placed between the CPU core and the instruction cache to service the instruction stream. Power savings in instruction fetch result from accesses to a small cache. In this paper, we introduce decode filter cache to provide decoded instruction stream. On a hit in t...

the harmonic in distribution systems becomes an important problem due to an increase in nonlinear loads. this paper presents a new approach based on a graph algorithm for optimum placement of passive harmonic filters in a multi-bus system, which suffers from harmonic current sources. the objective of this paper is to minimize the network loss, the cost of the filter and the total harmonic disto...
