5. Assume you got a wireless device with circuit power consumption of P_clee = 0.15m W. Frequency bandwidth (i.c. symbol rate) is 4MHz. You have a packet with 192 bytes to send. Assume there is no other overhead, and you can ideally turn on and off the transmission without additional power cost. Now you can choose using various data rates to transmit this packet, while maintaining a certain BER with the following assumption: using BPSK, the required TX amplifier power consumption of P_t -0.25mW; using QPSK, the required TX amplifier power consumption of P_1 -0.55mW. Receiver energy consumption is not a concern. Please calculate the energy consumption of transmitting this packet, in unit of Nano-Joule nJ (InJ = 10^-9 Joule), using BPSK and QPSK schemes, respectively (10 point)?
