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

INTRODUCTION
A PLL circuit is used to synchronize an output signal, which is usually generated by an oscillator, with a reference or input signal in frequency as well as in phase. In the synchronized state, the difference (error) between the reference and the oscillator output is zero or at least very small. So it is called locked
The phase-lock-loop (PLL) is commonly used in microprocessors to generate a clock at high frequency ( F out = 2GHz for example) from an external clock at low frequency ( F ref = 100MHz f ....etc

Closed loop timing



Bundled closed loop timing

Signal AD and ref signal Aclk transition tncq after each transition on Tclk
Vector BD and reference Bclk transition tnAB later.
Timing loop locks the quadrature clock Qclk to Bclk with offset lag equal to aperture offset ta0 of phase detector of flip-flop
This places the receive clock, Rclk which is offset from Qclk by /2
Aperture is exactly centred on the eye of data vector BD.

Which of these elements of timing uncertainty are cancelled?

Loop magnetic couplers

Couplers, also known as isolators because they electrically isolate as well as transmit data, are widely used in industrial and factory networks, instruments, and telecommunications. Every one knows the problems with optocouplers. They take up a lot of space, are slow, optocouplers age and their temperature range is quite limited. For years, optical couplers were the only option. Over the years, most of the components used to build instrumentation circuits have become ever smaller. Optocoupler t ....etc

An industrial plant has hundreds or even thousands of control loops. The performance of control loops is important to ensure high product quality and low cost of the product in such plants. In general, oscillatory variables are one of the main causes for poor performance of control loops. Therefore, detection and diagnosis of the causes of oscillations in control loops is very vital for maintaining the product within the desired quality limits. Identification of such source signatures is a very important task in assessing closed loop control pe ....etc

Open loop control vs. closed loop (feedback) control



The next two figures present the structures of open loop and feedback control systems.
Figure 1 shows an open loop control system whose function is to cause the output y(t) to follow the
reference r(t).
Feedback control system design for zero steady state error
In general, to follow a reference R(s) with zero steady-state error, the path between the
reference and the system output should contain a term like R(s). For instance, to follow a ramp

ABSTRACT
Fiber Channel is an ANSI interface that acts as like a general transport vehicle to simultaneously deliver the command sets of several existing interface protocols. Fiber Channel Arbitrated Loop is one topology used to connect two or more devices within the guidelines set by the ANSI standards. It supports both large and small data transfers, and can be used in systems ranging from supercomput ....etc
