Patent ID: 7512083

Claim:
A radio frequency (RF) multi-antenna access point system implemented in a single chip integrated circuit chip (IC) comprising: a baseband processor circuit located in a first portion of the single chip IC, the baseband processor circuit to handle data transmissions during a first operating mode in a channel between a first access point and a second access point; and a multi-antenna signal processing circuit located in an Application Specific Integrated Circuit (ASIC) in a second portion of the single chip IC, the multi-antenna signal processing circuit to handle data transmissions during a second operating mode in said channel, said multi-antenna signal processing circuit being further: (a) configured to receive M independent RF modulated input signals from said second access point; and (b) configured to process said M independent RF modulated input signals using a channel mixing matrix and estimated channel coefficients b 1 , b 2 to extract N independent data signals transmitted by said second access point; wherein said first operating mode and said second operating mode are to be automatically selected by the RF multi-antenna access point system based on a transmission condition in said channel.
