M-QAM bit error rate analysis of multipath channels in LTE system

In this paper, Long Term Evolution (LTE) Cellular networks provides higher bit rates and consequently higher spectral efficiencies. Quadrature Amplitude Modulation has been adopted by most wireless communication standards such as Long Term Evolution (LTE). We analyses the Bit error rate (BER) of M-ary QAM in both multipath fading channels such as Rayleigh fading and Additive white gaussian noise (AWGN) channels. The simulation shows between the BER and energy per bit to noise power spectral density.
