Determine theoretical data capacity of the wireless channel, Computer Networking

Assignment Help:

Consider a simple wireless data link using channel bandwidth of 40 kHz. The transmit power level is 20 dBm, the link attenuation is 40 dB and the SNRdB at the receiver is 20 dB. 

a)  What is the signal power at the receiver (in dBm and in mW)?

b)  What is the noise power at the receiver (in W)?  

c)  What is the theoretical data capacity of the wireless channel in question?  

d)  How many discrete levels of signal need to be used in the modulation scheme for the link to achieve a data rate of at least 60% of the theoretical capacity?
