Hello,
I'm designing LTE downlink using matlab. So I wonder if somebody help me with the parameters by answering the question below:
I've read the standard but to apply them on matlab I got convused.
- number of FFT points
- pilot location (is need extension)
- cyclic prefix
Is the subcarrier sam as the number of bit per symbol or are they different
last question, I got code from mathworks writen by Mohammad Tahir and he defined the SNR as below
Code:
EsNo= EbNo_dB + 10*log10(52/64)+ 10*log10(64/80); % symbol to noise ratio
snr= EsNo - 10*log10(64/80); % snr as to be used by awgn fn.
I only know that LTE has a 4.69 µs cyclic prefix and that it uses 2048 point FFT, I don't know whether the number of FFT points is changed with channel BW like WiMAX or not.
