Abstract: Data communication includes an estimate of packet error rate that is useful, for example, when there is insufficient data transmission to provide a direct measurement of packet error rate. At least one pilot channel output provides a basis to determine an estimated packet error rate. One example includes using a pilot channel ratio of an energy-per-chip to a noise spectrum density. Another example includes using a pilot symbol error rate from the pilot channel as the basis for determining the traffic channel packet error rate.
