An Improved SDR Frequency Tuning Algorithm for Frequency Hopping Systems

A Frequency Hopping Algorithm for Cordless Telephone Systems

In this paper a novel frequency hopping algorithm is introduced, which is tailored for use in a Cordless Telephone System (CTS) that relies on total frequency hopping to use the same frequency band as a GSM system.The algorithm was designed with the goal of minimising the interference between different CTS-units and between the CTS and the overlay GSM network, taking into account standard GSM i...

Evaluation Board for Frequency Hopping-cdma Systems

An evaluation board with FPGA (XC2S15) and 200MHz single-chip Direct Digital synthesizer (AD9857) has been designed to demonstrate a Fast Frequency Hopping CDMA (FFH-CDMA) implementation. The paper shows how the pseudo-random Gold code may determine the frequency hopping of the carrier in FFH-CDMA systems.

Multipath Delay Estimation for Frequency Hopping Systems

Frequency Planning for Slow Frequency Hopping System

Radio resources planning for frequency hopping military systems is very complex task due to the size of considered deployments, the radio resource limitations and the complexity of the radio phenomena to take into account. In this paper, we present some aspects of the local search algorithm proposed to deal with this problem. We focus more specially on the developed degradation control mechanis...

Load Frequency Control in Power Systems Using Improved Particle Swarm Optimization Algorithm

The purpose of load frequency control is to reduce transient oscillation frequencies than its nominal valueand achieve zero steady-state error for it.A common technique used in real applications is to use theproportional integral controller (PI). But this controller has a longer settling time and a lot of Extramutation in output response of system so it required that the parameters be adjusted ...
