GMSK DEMODULATOR USING COSTAS LOOP FOR SOFTWARE-DEFINED RADIO

ABSTRACT

DSP based implementation of Gaussian Minimum Shift Keying (GMSK) demodulator using Costas loop has been described. The demodulator consists of a Costas loop for carrier recovery, data recovery, and phase detection. For low data rates, we have tested the scheme on a TI s DSP TMS-320C6713. These are imple ....etc

Radio frequency identification (RFID) is currently the hottest technology in the area of wireless applications. Its unique advantages, such as data transmission with extreme low power or even no power on the label can be the biggest benefit to the management of goods. Software Defined Radio (SDR) is a wireless communications system in which all signal processing is implemented in software. Simply by downloading a new program, a software radio is capable of inter operating with different wireless protocols, incorporating new services and upgradi ....etc

What s the Software Defined Radio

Software Defined Radio (SDR) refers to the technology wherein software

modules running on a generic hardware platform consisting of DSPs and

general purpose microprocessors are used to implement radio functions

such as generation of transmitted signal (modulation) at transmitter

and tuning/detection of received radio signal (demodulation) at

receiver. a radio that includes a transmitter in
which the operationg parameters of the
transmitter, ....etc

Resistor
As you know the resistor is an inevitable part of a circuit. It is meant for reducing the current and voltage in the circuit parts. Resistors are identified using the standard colour code chart. A simple trick can be used to identify the resistor value range. The third colour band on the body of the resistor represents the multiplier value. So by identifying the third colour, it easy to know the value in range.
Maximum power handling capacity of Resistors is
Watt Max. 50mA, Watt Max. 70mA, 1 Watt Max. 1 ....etc

Introduction

Software-Defined Radio (SDR) Forum defines SDR technology as radios that provide software control of a variety of modulation techniques, wide-band or narrow-band operation, communications security functions (such as hopping), and waveform requirements of current & evolving standards over a broad frequency range.

In a nutshell, Software-Defined Radio (SDR) refers to the technology wherein software modules running on a generic hardware platform consisting of DSPs and general purpose microprocessors are used to implement radio ....etc

A Software Defined Radio (SDR) system is a radio communication system where components that have typically been implemented in hardware (i.e. mixers, filters, amplifiers, modulators/demodulators, detectors. etc.) are instead implemented using software on a personal computer or other embedded computing devices. While the concept of SDR is not new, the rapidly evolving capabilities of digital electronics are making practical many processes that were once only theoretically possible. A basic SDR may consist of a computer (PC) equipped with a sound ....etc
