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 ...
متن کاملPerformance Evaluation of Nakagami fading Channel for Frequency Shift Keying (FSK)
In this paper, the performance of these frequency shift keying communication systems over generalized fading channels. Wherever possible, we shall again make use of the desired forms rather than the classical representations of the mathematical functions the treatment here will be quit brief since indeed the entire machinery that allows determining the results has by this time been developed co...
متن کاملOn 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...
متن کاملOrthogonal chaotic vector shift keying in digital communications
An Orthogonal Chaotic Vector Shift Keying (OCVSK) digital communication scheme is presented in this paper. The main characteristics of the scheme are increased data transmission rates with greatly improved robustness and, an increase in security of communications links due to the structure of the scheme and the nature of the message bearer. Compared with some existing schemes, for example Quadr...
متن کاملOn-Off Frequency-Shift-Keying for Wideband Fading Channels
M-ary On-Off Frequency-Shift-Keying (OOFSK) is a digital modulation format in which M-ary FSK signaling is overlaid on On/Off keying. This paper investigates the potential of this modulation format in the context of wideband fading channels. First it is assumed that the receiver uses energy detection for the reception of OOFSK signals. Capacity expressions are obtained for the cases in which th...
