The compressed beam forming weights (CBWs) feedback is used in the IEEE 802.11n/ac WLAN, an example of the practical beam forming MIMO-OFDM system, to reduced the amount of feedback information. We can achieve gate count reduction by exploiting only one matrix triangulation module in our architecture. The VLSI implementation results under the TSMC 90ns CMOS technology reveal that our architecture reguires 194.25K gates while operating at frequency 200.75 MHz.

Abstract


The compressed beam forming weights (CBWs) feedback is used in the IEEE 802.11n/ac WLAN, an example of the practical beam forming MIMO-OFDM system, to reduced the amount of feedback information. We can achieve gate count reduction by exploiting only one matrix triangulation module in our architecture. The VLSI implementation results under the TSMC 90ns CMOS technology reveal that our architecture reguires 194.25K gates while operating at frequency 200.75 MHz.
