CFO limit for correct LTE Zadoff-Chu Synchronization
I am working with Zadoff-Chu sequences in a Python simulation of an LTE-like communication system and need to understand the effects of carrier frequency offset (CFO) on these sequences. … 2048
fs = N*15e3
carriers = slice(N//2 - 31, N//2+31+1) # OFDM carriers
symbol_time = N/fs
zc_freq = np.zeros(N, 'complex')
zc_freq[carriers] = zadoff_chu(25) # the root is one of the specified in LTE …

LTE PSS Channel Estimation for coarse SSS Equalization
In LTE the Primary Synchronisation Signal (PSS) can be detected by taking a correlation with the known 3 zadoff chu sequences (roots: 25,29,34). …
