"Even though a frequency offset introduces a time-varying phase error, as long as this error changes slowly relative to the symbol rate, the differential phase from...
Differential QPSK (DQPSK) is used with OFDM to transmit data over wireless fading channel. Is differential coding enough to solve the proplem of subcarriers phase...
Dear mukul,Your answer very clear and helped me alot, thansk for help,your words mean that i have to change sampling frequency, or frequency spacing to get power...
"Fs is only resident of digital domain and is lost in space" what do you mean with lost in space?What is the defects of increasing sampling frequency (Fs>>BW)?It...
Thanks Kaz for your simple explaination, another question please, the actual bandwidth required to transmit nFFT is fs (7.68MHz) or signal bandwidth (5MHz)?
Thanks David for your help, the example i work on the number of subcarriers 512 (power 2 number), bandwidth BW 2560 Hz and the frequency spacing 5Hz,the auther used...
Thanks sir, your wards "Now from discrete frequency domain you get still discrete, but time domain samples" that means the time and frequency domain signals are...
