A Novel Transformer-Based Single-to-Three Phase Conversion Technique Using Rotating Magnetic Field Theory

This paper presents a new single to three phase converter using rotating magnetic field transformer. Conventional transformers have been used in many converters aiming at supplementary improvements and they usually have no critical effect on the conversion technique. In this paper, the conversion technique is based on a special rotating magnetic field transformer in which there are two windings...

A Novel Approach for Frequency Hopping Cdma Technique

Frequency-Hopping Spread Spectrum (FHSS) is a method of transmitting radio signals by rapidly switching a carrier among many frequency channels, using a pseudorandom sequence known to both transmitter and receiver. It is utilized as a multiple access method in the frequency-hopping code division multiple access (FH-CDMA) scheme. A frequency-hopped spread spectrum multi-access network which is s...

A Spectrally Efficient Anti-Jamming Technique Based on Message Driven Frequency Hopping

This paper considers spectrally efficient anti-jamming system design based on message-driven frequency hopping (MDFH). Unlike conventional FH where the hopping frequencies are determined by a preselected pseudonoise (PN) sequence, in MDFH, part of the message acts as the PN sequence for carrier frequency selection. It is observed that MDFH has high spectral efficiency and is particularly robust...

Chaotic frequency hopping sequences

This letter describes a novel family of frequency hopping sequences generated by chaotic systems. The sequences give a uniform spread over the entire frequency bandwidth. In addition to having good Hamming correlation properties, they possess ideal linear span. The sequences produce almost as good performance as random hopping patterns when used in frequency hopping code-division multiple-acces...
