An implementation design of preamble detection based on LTE random access
In order to improve the efficiency of the preamble detection in random access
this paper proposes a frequency domain detection-based invariable threshold algorithm
which detects the signature preamble sequence on the basis of frequency domain detection by supposing the invariable threshold.Compared with the traditional time-domain detection algorithm
it reduces the complexity and is still simpler in the choice of threshold.Simulation results prove that this method shows good performances in various wireless channels.
