Demultiplexing of Signals on the Downlink OFDM in UTRAN-FDD

One problem which arises in analog communication or digital communications networks in telecommunications, especially in third generation cellular networks, is the signal reception without a total degradation of the transmitted signal. In this paper, the authors have analyzed the received signal without multipath at Additive White Gaussian Noise (AWGN) with a Signal to Noise Ratio (SNR) per sample, 10 dB, 8 dB, 6 dB and 4 dB respectively. They present the received signal with a multipath channel with noisy, the signal to noise ratio of 6 dB is studied and a multipath channel noiseless. And doing these studies, they considered the impulse response.
