Can someone please give me the answer of following question. the transmitter operates at a frequency of 1GHz, it is connected to an antenna of gain 10dB. the cable connecting the transmitter to the antenna has a loss of 3dB. the reciever has an antenna with a gain of 0dB and there is no other loss at the reciever. the distance between the transmitter and the reciever is 6km. the double sided noise power spectral density at the reciever, No/2 is 10e-16 W/Hz. assuming free space path lose between the transmitter and the reciever antennas. calculate the power needed at the transmitter to maintain a demodulater BER of less than 10e-3 ?

i have some queries. can someone please provide me the answers of following questions. i'll be very grateful 1: draw a diagram of the encoder for the code 101010001(14,6), t=1, and information bits 000011. 2: the demodulated bits are passed to an error correcting decoder. draw a diagram of a decoder for the code shown above. 3: encode the information bits as shown above. 4: the encoder output (from question 1)is in NRZ format and is then modulated using PSK. produce a diagram of the NRZ waveform and the corresponding PSK waveform.
