Performance Analysis of M-ary CSK Based Transform Domain Communication System
نویسندگان
چکیده
Transform domain communication system (TDCS) has been proposed as a new kind of intelligent wireless communication system, which has the advantages of adaptive interference avoidance capability and low probability of intercept (LPI). Different from the traditional communication system suppressing interference at the receiver, TDCS synthesizes an adaptive fundamental modulation waveform (FMW) in the transform domain which evades the interference regions at the transmitter. In this paper we investigate the system performance of the TDCS by exploiting M-ary cyclic shift keying (CSK) modulation. The numerical results show that the M-ary CSK based TDCS can provide low bit error rate (BER) in the presence of single tone interference. With the increase of the order M-ary, the system has significant BER improvements. Furthermore, the transmission bit rate and bandwidth efficiency are also increased by the M-ary CSK based TDCS. Key-Words: Interference avoidance, low probability of intercept, M-ary cyclic shift keying, transform domain communication system, fundamental modulation waveform.

The performance of Orthogonal Frequency Division Multiple Access (OFDMA) system degrades significantly in doubly dispersive channels. This is due to the fact that exponential sub-carriers do not match the singular functions of this type of channels. To solve this problem, we develop a system whose sub-carriers are chirp functions. This is equivalent to exploiting Fractional Fourier Transform (F...
