For Eb/No values of [-3,35], generate data bits that would be transmitted via a BPSK communication system with Rayleigh fading channel and AWGN noise. At the receiver side: a. Equalize the received signal (simply by dividing the received signal by the channel coefficients).
b. Design the BPSK demodulator (if received signal is +ve then the data bit=1 otherwise the data bit =0)
c. Count the number of bits in error and the BER.
d. Compare with the theoretical BER in AWGN channel.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k
