4. A battery operated sensor transmits to a receiver that is plugged in to a power outlet. The device is
continuously operated. The battery is a 3.6 V coin-cell battery with a 245mAHr capacity.
The application requires a bit rate of 36 Mbps and an error rate of less than 10^-3. The channel has a
center frequency of 2.4 GHz, a bandwidth of 10 MHz and a noise power spectral density of 10^-14
W/Hz. The maximum distance is 36 meters and the losses in the channel attenuates the signal by 0.25
dB/meter.
Your company has two families of chips that you can use. An M-ary ASK and an M-ary QAM chip. The
have very different power requirements as shown in the table below.
The total current for the system is the current required to achieve the desired Eb/No PLUS the current
identified below:

Using the 802.11a specifications given below, in Matlab (or similar tool) create the time domain signal
for one OFDM symbol using QPSK modulation. See attached plot for the QPSK constellation.
Your results should include the power measure in the time and frequency domain and comment on
those results.
