Definitions
- FIG. 6 is a block diagram illustrating equalization components of a baseband processing module according to a first embodiment of the present invention
- the radio 204 receives outbound data 250 from the host processing components via the host interface 220 .
- the host interface 220 routes the outbound data 250 to the baseband processing module 222 , which processes the outbound data 250 in accordance with a particular wireless communication standard (e.g., UMTS/WCDMA, GSM, GPRS, EDGE, et cetera) to produce digital transmission formatted data 252 .
- the digital transmission formatted data 252 is a digital base-band signal or a digital low IF signal, where the low IF will be in the frequency range of zero to a few kilohertz/megahertz.
- the operations of FIG. 13 may be performed on received MIMO signals.
- the following equations (viewed in conjunction with the operations of FIG. 13 , the baseband processing module 222 of FIG. 12 , and the channel model of FIG. 10B ) may be employed by embodiments of the present invention upon received MIMO signals.
- the MIMO signal model may be characterized as:
