Amplitude Shift Keying & Frequency Shift Keying

Aim: To generate and demodulate an amplitude shift keyed (ASK) signal and a binary FSK signal. Amplitude shift keying-ASK-in the context of digital communications is a modulation process, which imparts to a sinusoid two or more discrete amplitude levels. These are related to the number of levels adopted by the digital message. For a binary message sequence there are two levels, one of which is ...

On Coded M-ary Frequency Shift Keying

We discuss the combination of permutation codes and M-ary frequency shift keying. We show that this combination has special properties that can be used in power-line communications: e.g. constant envelopes, and error correction capability for impulsiveand narrow band noise. We give a simple convolutional encoding and decoding scheme. The outputs of a binary convolutional codes are mapped onto c...

Effect of Laser Frequency Offset on Optical Minimum-shift Keying Transmission System

As a special case of continuous phase frequency-shift-keying (FSK), minimum-shift keying (MSK) exhibits some different properties compared with the traditional optical phase modulation formats, such as return-to-zero (RZ) differential-phase-shift-keying (DPSK) and differential-quadrature-phase-shift-keying (DQPSK). In this paper, we investigated the receiver performance degradation caused by la...

Zero-Crossing Based Demodulation of Minimum Shift Keying

Minimum shift keying (MSK) modulation has features such as constant envelope, compact spectrum and good error performance, which are all desirable in many digital applications including mobile radio. Numerous receiver structures to demodulate MSK have been suggested, such as correlation receivers, differential detectors and frequency discriminators. MSK is a form of biphase keying and can be de...

A Baseband Pulse Shaping Filter for Gaussian Minimum Shift Keying

Gaussian pulse shaping is used in digital communication systems like DECT, GSM,WLAN to minimize the out of band spectral energy. The baseband rectangular pulse stream is passed through a lter with a Gaussian impulse response before frequency modulating the carrier. Traditionally this is done by storing the values of the pulse shape in a ROM and converting it to an analog waveform with a DAC fol...
