In Terahertz frequency band there is an abundant of bandwidth available to achieve ultra-high speed wireless communication to achieve data rates of 100 Gbps. We choose Parallel Sequence Spread Spectrum (PSSS) as an analog friendly modulation and coding scheme that allows for an efficient mixed-signal implementation of a 100 Gbps wireless baseband. Rapp Model is a ‘behavioural amplifier model’ which characterize the AM/AM conversion of a solid-state high power amplifier. In this paper, a PSSS modulated signal is transmitted through a “Rapp Model”, then through an AWGN channel and finally a PSSS demodulator which recovers the signal and performs BER calculations. We have to investigate as on how much non-linearity induced by PA can PSSS modulated system tolerate and still be able to recover the transmitted data at the receiver.
