Abstract
The outage and Average Bit Error Rate (ABER) performance of a single-channel Digital communication system in One Wave Diffused Power (OWDP) fading are obtained. The probability density function (pdf) is used to obtain the expressions for outage probability, and ABER for coherent and non-coherent modulation. The effects of the types of coherent BPSK, Binary Frequency-Shift Keying (BFSK), M-ary PSK, Rect.Quadrature Amplitude Modulation (QAM) and non-coherent Differential Binary Phase-Shift Keying (DBPSK), BFSK and M-ary FSK, and the fading parameter K on the system performance have been studied. The results are therefore obtained and verified with the results found in literature.

Response to Review 2 (Reviewer C)’s comments
We sincerely thank the esteemed reviewer for reviewing our work and for giving useful comments. Our responses (R) can be found immediately below his/her comments (C).

C: Ref [1] states TWDP captures widest breadth of fading and important similarity then what is the motivation significance of using OWDP.
R: The OWDP fading model comprises one specular component and many diffused component. The OWDP fading model is a special case of TWDP fading model. We did not find any work related to this fading channel. Hence, we derived the expression newly instead of considering OWDP fading channel as a special case of TWDP fading channel.

C: References of Eqs. 1 and 2 not stated.
R: The reference of Eq. 1 has been stated as per suggestion. The expression in Eq. 2 has been derived from Eq. 1. Therefore, the reference no. of Eq. 2 has not been stated in the paper.

C: Reference of Eq. 5 is not [11] but [14]. Figure 3 caption is not as per the format.
R: The changes have been made in the paper as per suggestion.

C: In Fig. 2 why before 2 dB the performance of BFSK is better than BPSK.
R: The performance of BFSK is better than BPSK before 2Â dB. The reason behind this is that the region before 2Â dB is noise dominant. In BFSK the information is stored in the frequency variation of the signal. The noise can easily affect the signal carrying information in frequency variation. The result obtained in this manner is insignificant and erroneous.

C: Why K = 5 is taken for Fig. 3 Not explained. The conclusion need to be elaborated in terms of significance and application
R: The figures can be plotted for any values of K. The change has been made in the plot of Figs. 2 and  3. The figures of Figs. 2 and 3 have been made for K = 5 and K = 7. The changes have been made in the conclusion as suggested.
