2-Consider a wireless bandpass channel with bandwidth of 1 MHz and channel-time dispersion of 10 microseconds. i)lf data transmission by this channel is implemented as a single carrier system with symbol duration equal to 1 microsecond, does this system requires an equalizer or not? Justify your answer.(3 points) ii)If, instead of a single carrier, a multicarrier OFDM is employed, determine the number of subchannels .(3 points) iii) In order to cancel the ISI resulting from OFDM symbols, a CP with the duration of 8 microseconds is used . Assuming 16QAM modulation for any subchannel, compute the system bit rate . In this case, what will be the percent of rate loss due to the CP? (4 points) { x=0.1y = x<<y}
