20100061489	Power Saving Apparatus and Method of Multiple-Antenna Receiver with Variable Rate - A multiple-antenna receiver can enable and disable receive radio frequency front-end and analog front-end circuits of specific antenna receiving routes according to a predetermined scheme during the receive data phase. The predetermined scheme calculates signal quality indices of the receiving route antennas by means of a preamble sequence, and derives the modulation and coding scheme and the number of spatial streams via the information provided by a header sequence. Indications of the signal quality indices are compared with threshold values to determine which receiving routes are to be turned on and which receiving routes are to be turned off.	03-11-2010

20080280566	WIRELESS COMMUNICATION APPARATUS WITH BUILT-IN CHANNEL EMULATOR/NOISE GENERATOR - The invention provides a wireless communication apparatus with performance simulation function. The wireless communication apparatus includes a channel emulator and at least one noise generator; therefore a real transmission environment can be simulated inside the wireless communication apparatus to thereby accelerate the testing process. Moreover, as this invention sets a random noise generator in front of the FFT, an approximate AWGN effect will be generated when the wireless communication apparatus is under test.	11-13-2008
