“…The above mentioned Gaussian filter introduces overlapping of the transmitted signal, and this causes the degradation and it is small if the 3 dB bandwidth bit duration product (BT) is greater than 0.5 values (Sadkhan et al, 2014). This ISI occurred by the channel can be controlled by filtering the shaped pulses (Nguyen et al, 2016). Earlier initially, the input data is in the form of NRZ, data and it is given to a pulse shaping filter (Gaussian filter) before feeding them to the LFM modulator.…”

“…In this paper, the same filter design will also use in the receiver section and is equally proportioned in the form of matched filter. Pulse shaping is an important task performed on the transmitter side and in order to reduce the effective bandwidth during transmission suitable Gaussian low pass filter is used (Nguyen et al, 2016). The choice of bandwidth B and bit-rate T is a compromise between spectrum efficiency and BER performance (Said, El-Henawey, & El-Kouny, 2013).…”

“…Digital phase modulation system involves sending information through channel either by varying the physical quantities and it is smoothed by using pulse shaping filter. The requirement of pulse shaping filter is effective against eliminating spectral leakage, reducing the channel width and also to eliminate the ISI (Nguyen et al, 2016). This result in a very compact signal spectrum and better utilization of available bandwidth.…”

Outstanding advantages of OFDM helps high data rate communication systems such as Digital Video Broadcasting (DVB) and mobile worldwide interoperability for microwave access (mobile Wi-MAX). But, OFDM system grieves from grave issue of high PAPR. In OFDM system data output is superposition of multiple sub-carriers and leads to big data. In this case some instantaneous power output might increase greatly and become far higher than the mean power of system. In order to make Neutrosophic data for less PAPR criteria, Gaussian filter based Costas coding is proposed. This paper also proposes feeding the Orthogonal Frequency Division Multiplexed signal (OFDM) into a phase accumulator to obtain frequency modulation, with the aim of reducing the peak to average power ratio (PAPR). For associated radar with modulated waveform mentioned here can be used to enhance the performance. It is widely used to analyze the variation of the output waveform further, the implementation results using MATLAB show that the ratio of average power to peak power is reducing considerably in comparing with the conventional method. Consequently; the signal can assume to fade in a frequency selective channel without an equalizer.
