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 کاملFrequency-shift keying for ultrawideband - achieving rates of the order of capacity
In wideband systems that decorrelate in time and frequency, capacity can be reached in the limit of infinite bandwidth by using impulsive frequency-shift keying (FSK) with vanishingly small duty cycle. The richness of the codebook is then created through the large bandwidth, thus requiring very large bandwidths in order to approach capacity. We show that FSK with small duty cycle can achieve ra...
متن کاملFrequency - shift keying for Ultrawideband - How close to capacity can we get ?
In wideband systems that decorrelate in time and frequency, capacity can be reached in the limit of infinite bandwidth by using impulsive frequency-shift keying with vanishingly small duty cycle. The richness of the codewords is then created through the large bandwidth. We show that frequencyshift keying with small duty cycle, using traditional random coding arguments, can achieve rates close t...
متن کاملAn Efficient Space-time Coding for Wireless Communications with Offset 4 - Phase Shift Keying
Channel capacity has long been a block in wireless communications. Various approaches are present in the literatures which are very effective in enhancing signal reception quality in fading channels. Various multiple antenna approaches have been used in wireless communications to combat the fading effect, which enhances both the channel capacity and performance greatly. Transmit Antenna Selecti...
متن کاملPrecoded orthogonal frequency division multiplexing with hidden pilots for ultrawideband wireless communications
The authors propose a new hidden pilot scheme equipped with precoding and its application to orthogonal frequency division multiplexing-ultra-wideband (OFDM-UWB) systems. The proposed scheme can be thought of as an improvement over conventional hidden pilot schemes. By carefully designing precoder and hidden pilot from the view point of frequency diversity, channel estimation and the peak-to-av...
