generating an effective signal-to-noise ratio value from the signal-to-noise ratio values; and determining, from the effective signal-to-noise ratio value, a value for the BER estimate.
- 4. A method for use in wireless equipment, the method comprising the steps of:
processing a received wireless signal to provide a number of signal-to-noise ratio values over a time period; generating an effective signal-to-noise ratio value from the signal-to-noise ratio values; determining a Bit-Error-Rate (BER) estimate for the received wireless signal as a function of the effective signal-to-noise ratio value.
- 5. The method of claim 4 wherein the determining step uses the effective signal-to-noise ratio value as an index into a table to retrieve the BER estimate therefrom.
- 6. Apparatus for use in wireless equipment, the apparatus comprising:
a receiver element for demodulating a received wireless signal and for providing a number of signal-to-noise ratio values associated with the received wireless signal; and a processor for providing a Bit-Error-Rate (BER) estimate for the received signal as a function of the number of signal-to-noise ratio values.
