Abstract
Aspects of the subject disclosure may include, for example, receiving, by a first radio module at a first location, a wireless MIMO signal, to obtain a first received RF signal. The wireless MIMO signal includes information originating at a remote MIMO transmitter and conveyed via a wireless channel. An envelope of the first received RF signal is detected by the first radio module without requiring a local oscillator, to obtain a first baseband signal. The first baseband signal may be filtered and/or amplified, after which it is compared to a reference value to obtain a first digital signal that is provided to a digital processor. The digital processor also obtains a second digital signal from a second radio module receiving the wireless MIMO signal at a second location and determines an estimate of the information originating at the remote MIMO transmitter according to the first and second digital signals. Other embodiments are disclosed.
