[JSP] mergejliin-dadlaga-zurag DL : 0: In this transmission system, the input signal bits are first mapped into complex-valued symbols {sn}, according to its modulation type. The in-phase and quadrature components of the symbol will be multiplied with the high frequency carrier and be transmitted over the additive white Gaussian noise (AWGN) channel. On the demodulator side, the received signal is demodulated with correct carrier phase into its in-phase and quadrature components, and sampled with the correct timing intervals, ts=nT. The equalizer can be considered as a part of the demodulator. The input to the equalizer is the {rn} sequence, which represents the complex-valued symbols with ISI distortion, and the output is the soft decision result, which is the probability of each received bit being „ 1‟ or „ 0‟ .-In this transmission system, the input signal bits are first mapped into complex-valued symbols {sn}, according to its modulation type.
