1. MIMO Systems- explain the benefits of 2Tx/1RX vs 1Tx/2Rx 2. 10 wires with each having 2 ends are inside a bag. 2 ends can be connected to form 1 notch. The total number of possible notices are 1 to 10. Find the expected value of possible number of notches. Explain the process. 3. Given a PDF with an exponential distribution of lambda(e^-lambda x) explain how to find lambda given ten independent observation points. 4. given a complex system of -1 to +1 KHz, determine the Nyquist rate and what under what conditions will aliasing occur. If the bandwidth was triangular shaped, what will the resulting shape be when Fs is 2 KHz.
