Prach filtering
WebDownsampling by an integer factor. Rate reduction by an integer factor M can be explained as a two-step process, with an equivalent implementation that is more efficient:. Reduce high-frequency signal components with a digital lowpass filter.; Decimate the filtered signal by M; that is, keep only every M th sample.; Step 2 alone allows high-frequency signal … WebIntroduction. The Random Access Channel (RACH) is an uplink transmission used by the User Equipment (UE) to initiate synchronization with the eNodeB. TS36.104, Section 8.3.4.1 [ 1 ] defines the probability of Physical Random Access Channel (PRACH) detection must be greater than or equal to 99% at an SNR of -8.0 dB.
