The signal to noise ratio at the receiver is required to be at least 17 dB. The average noise power at the receiver is 1 mW. The cable loss between the transmitter and the receiver is 2.5 dB/km and there is 55 km of cable between the transmitter and the receiver. There is a 25 dB amplifier between the transmitter and receiver. Determine the transmit power at the transmitter to achieve a signal to noise ratio of 17 dB at the receiver?
Assume a CDMA system has only 4 walsh codes. If the mobile is assigned W4 and receives a data stream of 11011010, what is the output?
Determine the Laplace transform of the above signals (use properties of the Laplace transform) including the corresponding region of convergence.
To digitally manipulate information we must encode it using binary numbers. Consider an encoding for playing cards. There are 52 cards in a deck and they are divided
What is the bandwidth occupied by this signal, and the noise bandwidth of the receiver for this signal? Find the BER at the receiver output and the average time between errors.
Suppose the information portion of a packet contains 10 bytes consisting of the 8- bit unsigned binary ASCII representation of string "Link Layer".
Solve the equation z^2+z+1=0 using z=(x,y) and the basic definitions. (Hint: Note that y does not equal 0 because the equation X^2+X+1 does not equal 0 for any real number x.)
Write the expression for the current through the capacitor after the switch is closed. The circuit is a 60 Volt circuit
