1. A method of improving error detection in a communication system, the method comprising:

  • receiving an uplink signal from a transmitter at a receiver wherein the uplink signal contains a data portion and a transmitted result of a hash function, wherein the uplink signal is received at a time based on a slot start time and a random timing offset, and further wherein the uplink signal is received while at least a portion of a second signal is received from a second transmitter;

    measuring a noncoherent energy metric for the uplink signal;

    computing a local result of the hash function using the data portion; and

    discarding the uplink signal if the transmitted result matches the local result, but the noncoherent energy metric is below a threshold value.
