Re: Ofdma_ partial transmit sequence
computational complexity depends on number of process that pass through system. may be multiplication and addition process. in PTS, length of phase rotation equal than length of subblock, so multiplication occur in all subblock with different value of phase...
according to your script, we can say that 'numRun'. as number of symbols
the problem is we run with a lot of symbol, and every symbol must choose the lowest papr, every symbol has their own phase rotation
Re: Ofdma_ partial transmit sequence
phase rotation use to rotate the phase of OFDM signal
as i know, there are two kind phase rotation i.e phase rotation with weighting factor W=2 and phase rotation with weighting factor W=4
weighting factor W=2 using +1 and -1
weighting factor W=4 using...
Re: Ofdma_ partial transmit sequence
partial transmit sequence is a methode for reducing PAPR by divide bit stream into few subblocks then multiply the subblocks with few combination of phase rotation, and choose the lowest PAPR each subblock.
for example:
we have signal X...
Re: dvb-t
Least square is one of equalizing methode using part of pilot for estimating the block signal at all. i use LS by divide block signal by the first frame pilot
dvb-t
Do you simulate dvb-t using simulink or matlab script?
i have simulated dvb-t with least square equalization using matlab script in rician and rayleigh fading. i think least square(LS) is the simplest methode
