Abstract: Current system for communications utilize wireless for data transmission to exchange the information between associated mobile devices. The researchers are exploring novel methods to use the devices efficiently, faster and accurate. The ever increasing demand for new features by the user is making the industry standards to grow at a faster pace. The parameter like Bit Error Rate (BER) and Signal to Noise Ratio (SNR) are considered to understand the network performance. In this research paper, the transmission of different formats of video over the 4G LTE is carried amongst two systems using Wi-Fi. Different frames having various colour, size, black and white and video of different formats like .avi, mov, mpeg4 videos are transmitted. The frames are transmitted with and without channel. The transmission time and end delay parameters are observed. The performance of LSE algorithm in the OFDM channel is estimated. BER is estimated for low SNR using M-PSK modulation and LS algorithm. The M-PSK& BPSK are compared with each other and M-PSK found to give better result for low SNR with low BER. Rayleigh, Rician& AWGN noise is compared with each other and it is observed that Ricon gives better result. The channel length of 4, 16, 64 is taken to compare the SNR with BER. For low SNR, BER is low with less number of channels.
Keywords: SNR, BER, Pilot Channel.
