Open the CIPO recordAbstract From the Canadian patent
In a UMTS (universal mobile telecommunications system) based system a, wireless receiver implements "effective signal-to-noise (E b/N o) based BER estimation." In particular, the wireless receiver comprises a rake receiver a , processor, and memory. The rake receiver processes a received signal and provides signalto-, noise ratio values for each slot of each received frame of the received signal. The, processor converts these signal-to-noise ratio values for each received frame into an, effective signal-to-noise ratio value for the received signal. The processor then uses, the effective signal-to-noise ratio value as a pointer or index, into a look-, up table, (stored in the memory) and …

Why it's free to use
- Filed January 23, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 23, 2022.
