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 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 کاملErgodic Cmos Shift Keying
A new method to decode digital information coded onto a chaotic signal is introduced. It is designed for large spreading factors. It is based on the ergodicity of the chaotic system. This allows a partially analytical analysis of the system. An example using a one-dimensional map is elaborated in detail. The performance of this example is not yet competitive with classical systems for an AWGN c...
متن کاملTwisted Amplitude Phase Shift Keying
Several modulation techniques are defined in digital modulation, Here we are discussing about in four modulation techniques,8-PSK,8-TAPSK,16TAPSK and 16-QAM. In the paper we derive minimum non coherent distance(dnc)of block coded TAPSK and compare it with different modulation techniques, i.e. 8-PSK and 16-QAM using linear component codes. If the block length N is very small.NBC-16-TAPSK perform...
متن کاملAdaptive generalized space shift keying
In this article, we propose a closed-loop precoding method for the Generalized Space Shift Keying (GSSK) modulation scheme, suitable for Multiple-Input-Single-Output (MISO) systems and denoted as adaptive GSSK (AGSSK), which achieves transmit-diversity gains in contrast to GSSK. For the case of a perfect feedback channel, we analytically show that for three and four antennas at the transmitter ...
