DVB-T2 pilot insertion PN sequence used in the reference sequence ????!!!!
hi everybody ;h r u??
i am working on the ofdm transmission and reception part in DVB-T2 standard
so for the pilot insertion there is something called reference sequence which uses both PRBS and PN sequences.
my problem is that for the PN sequence i am not given any polynomial generator equation, i am only given the maximum length for each FFT mode and PN sequence frame level hexadecimal description
so can any one please tell me how to implement this PN sequence using matlab ????? or in other words how to get the polynomial equation based on the previously mentioned situation ????
note that it also said in the standard :The overall PN-sequence has been optimized by fragment by using as starting point the fully optimized short PN-sequence of length 15. Each relevant length of a given PN-sequence derives from this latter sequence
i don't understand this statement, can any one explain it, i think it may help
thanks in advance
