Consider a (Nt,Nr) =(4,4) MIMO channel. For the input of the channel x = [x1,x2,x3,x4] assume that each xi is drawn from a BPSK constellation with energy P. Also assume that the channel noise variance is σ2 = 1 From question 1, for the energy levels P = 0.1, 0.5, 1, 5, 10. implement the Zero-Forcing SIC detection method and find the estimate Zzf. is Zzf = x? If no declear an error.
Develop a logic circuit whose output is high when the input has had three consecutive ones to the input. Overlapping threes are allowed. (e.g., x=011110110 then the output z=000110000 assuming starting state was 0).
ASSUME THE NSC HAS A NEW INSTRUCTION CALLED INC (OPCODE = "11") THAT INCRMENTS THE CONTENT OF THE OUT REGISTER; THE INC INSTRUCTION DATA FIELD IS UNUSED. ALSO ASSUME THAT THE LOC INPUT IINPUT IS TIED TO THE COMPLIMENT
Using a 4-bit synchronous counter and an AND gate, construct a counter that counts from 0000 through 1010. Repeat for a count from 0000 through 1110. Minimize the number of inputs to the AND gate.
What is the out put voltage of an op amp circut if it has an ambient temperature of 50 degrees celcius and the thermistor Rt resistance is 810 ohms, The voltage in is positive 5 VDC and the only other resistort is 1000 ohms
A farmer owns two barns; one north of a creek and the other south of the creek. The farmer has a Cabbage, a Goat, and a Wolf. The Farmer needs to put each item in a barn every night. If the Cabbage and Goat are in the same barn
A device operates at 30 degree C with a bandwidth of 8 KHz anda dccurrent of 1.75 ma. Find the total noise power, moise current and equivalent noise voltage.
a)What is the voltage across a 220? resistor if the current through it is 5.6 mA b)What is the current through a 6.8? resistor if the voltage drop across it is 24 V c) What is the power delivered by a 6 V battery if the current drain is 750mA
You are designing a 2.4 GHz receiver with a 140 MHz IF. System design constraints require that the local oscillator power be minimized to reduce the potential for interference to other systems as well as to reduce the receiver power consumption.
Design a sequential circuit which adds two to a binary number in the range 0000 - 1001. The input and output should be serial with the least significant bit first. Find a state table with a minimum number of states.
A CS amplifier utilizes a MOSFET with unCox=400uA/V^2, W/L = 10 and Va = 10V. It is biased at Id = 0.2 mA and uses Rd = 6k Ohm. Find Rin, Avo and Ro. Also, if a load resistance of 10k Ohm is connected to the output
Find the unit impulse responses of two systems specified by these equations and comment on their similarities and differences: 1) (D2 + 4D + 3) y (t) = (D + 5) x (t) 2) (D2 + 5D + 6) y (t) = (D2 + 7D + 11)x (t) .
what is the theoretical minimum system bandwidth needed for a10Mbits/sec signal using 16-level PAM without inter sysmbol interference how large can the roll off factor be if the allowable system bandwidth is 1.375 MHz.
