Wireless communication has unfolded significantly over the times. In wireless communication system, the phenomenon of fading requires careful scrutinization so as to get efficient data reception at the receiver side. Various factors are responsible for this process namely, multipath propagation and shadowing. This case leads to instability or swings in the received signal and hence limits the performance of contemporary world's most crucial method of data transmittal. This deviation can be either in the signal amplitude, phase or degree at which signal; is entering the receiving antenna. Performance analysis of wireless communication deals with complicated and cumbersome task but a necessary one. Various fading models have been devised in order to interpret the attributes of the channel. TWDP (Two Wave Diffused Power) fading model is the general one that can be used to frame other fading models such as Rayleigh, Rician, etc. This model is much advantageous in studying the real world scenario. TWDP fading comprises of two multipath components with presence of propagating waves. In this paper the main focus will be on performance evaluation of BPSK and DPSK schemes in TWDP fading environment. Available PDF expression in the form of Bessel function, fading parameters and order of approximation is used to check the SNR at the output of the receiver. This articulation is further used in order to study various parameters followed by the comparison between the two modulation techniques.
