Generate root Zadoff-Chu sequence of complex symbols
SEQ = lteZadoffChuSeq(R,N)
The function generates the actual sequence using the following algorithm:
This function uses a negative polarity on the argument of the exponent or a clockwise sequence of phases.
Generate the 25th root length-139 Zadoff-Chu sequence.
lteZadoffChuSeq to generate the sequence and then plot its absolute values.
seq = lteZadoffChuSeq(25,139); plot(abs(xcorr(seq)./length(seq)))
