1. An apparatus for a base station, comprising:
receiver circuitry to receive at the base station, a signal from a user equipment (UE) transmitter to access resources of the base station;
statistics circuitry to calculate higher-order statistics on the signal to produce an identification indication, wherein to calculate the higher-order statistics, the statistics circuitry is to use estimates of the higher-order statistics of impairment of the signal;
a memory device to store the higher-order statistics and the identification indication; and
processing circuitry to:
associate the identification indication with the UE transmitter;
use the identification indication to determine that multiple failures of a random access channel (RACH) process have occurred from the UE transmitter; and
restrict later attempts by the UE transmitter to perform RACH processes with the base station.
