Twisted 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 کاملAmplitude 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 کاملRECOMMENDATION ITU-R F.763-5* Data transmission over HF circuits using phase shift keying or quadrature amplitude modulation
The ITU Radiocommunication Assembly, considering a) that there is an increasing demand for high-rate data transmission; b) that to meet this need, two types of phase-shift keying (PSK) modems may be used, namely parallel transmission modems using multi-channel voice frequency telegraphy and serial transmission modems using a single sub-carrier; c) that to compensate for the unfavourable nature ...
متن کاملM-ary amplitude shift keying OFDM system
Coherent M-ary ASK is proposed to be used in OFDM systems. The frequency separation between subcarriers is only 1/2T instead of 1/T. With a slightly wider bandwidth, an M -ary ASK-OFDM can achieve the same BER of M-ary QAM-OFDM and a better BER than that of MPSK-OFDM. The M -ary ASK-OFDM has the same Peak-To-Average-Power Ratio (PAPR) as that of the M-ary QAM-OFDM. The MASKOFDM can be implement...
