Implementation of Digital Signal Processing: Some Background on GFSK Modulation
In the context of this example, the alphabet has only two symbols 0 and 1. When the alphabet consists of just two symbols, the symbols are called bits. The modulation method is a variant of frequency modulation (FM) of some carrier frequency ωc. Frequency shift keying (FSK) conveys information by decreasing the carrier frequency for the duration of a 0 symbol and increasing the frequency for th...
متن کاملDesigning a GFSK Receiver in Arx
This technical note documents the design of a GFSK receiver in Arx. While GFSK is used in many telecommunication standards, the version described here uses toy parameters that are not related to any standard. The code is distributed as free IP on the Bibix website.1 The note starts by a presentation of the theory and then spends some attention on how Arx can be combined with testbenches in IT++...
متن کاملAutomatic calibration of modulated fractional-N frequency synthesizers
The focus of this research has been the development of a low power, radio frequency transmitter architecture. Specifically, a technique for in service automatic calibration of a modulated phase locked loop (PLL) frequency synthesizer has been developed. Phase/frequency modulation is accomplished by modulating the feedback divide value in a phase locked loop frequency synthesizer. A digital prec...
متن کاملLow-IF Receiver Planning for The DECT System
In this paper, low-IF receiver planning for Digital European Cordless Telephone (DECT) systems operating around 1.9 GHz is described. A low-IF receiver architecture is chosen, since it allows a high degree of integration. Unlike zero-IF receivers, this architecture does not have a DCoffset or self-reception problem. The main features of the DECT system are presented, including the translation f...
متن کاملAdaptive Digital Beamforming Antenna Array for High Speed Communications
The rapidly increasing demand for PCS has provided the impetus to design adaptive antenna arrays to improve spectral efficiency and enhance system capacity. With increasing data rate in some PCS application like DECT( Digital European Cordless Telecommunications), higher BER would degrade the system performance further. An adaptive antenna array testbed using 12 elements was built to evaluate i...
