LTE PRACH DETECTION IN LTE TOOLBOX

5 次查看(过去 30 天)
Hi all,
I am a newbiee with lte toolbox and would really appreciate if some one could help me.
I am going through the prach detection function from lte toolbox; lteprach detect and i could not get around this code shown below.
% The following parameter specifies the fraction of the timing window at
% the end of the timing window for one preamble that will be considered
% as belonging to the next preamble and having a timing offset of zero.
% This effectively excludes timing offsets of above (1.0-deadzone) of the
% maximum and ensures detection of preambles with low timing offset where
% noise has caused the peak of the correlation to be slightly into the
% previous preamble's timing window. The value configured below corresponds
% to the duration of the main lobe of the autocorrelation of the PRACH.
% (zero is used for the case that NCS=0 as there is only one preamble
% per correlation.)
if (zcz~=0)
deadzone=info.SamplingRate/(info.NZC*info.SubcarrierSpacing)/zcz;
else
deadzone=0;
end
I would be great if someone could help me out.
I am following a textbook named LTE:From theorey to practise but could not find anything about it.
It would be great if any refernce is provided to understand this.
BR,
Sri
