  • Patent number: 11664840
    Abstract: Aspects of the subject disclosure may include, for example, receiving, by a first radio module at a first location, a wireless signal, to obtain a first received RF signal. The wireless signal includes information originating at a remote 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 provided to a processor. The processor also obtains a second digital signal from a second radio module receiving the wireless signal at a second location and determines an estimate of the information originating at the remote transmitter according to the first and second signals. Other embodiments are disclosed.

  • Publication number: 20230006871
    Abstract: Aspects of the subject disclosure may include, a non-linear energy detector that obtains baseband information from a mixed signal that corresponds to an information component of a received radio frequency (RF) signal, wherein the mixed signal comprises a local oscillator signal combined, without multiplication, with the received RF signal, wherein the received RF signal comprises a carrier wave component operating at a carrier frequency within a millimeter wave spectrum, wherein the non-linear energy detector is associated with a non-linear current-voltage (I-V) characteristic curve, and wherein the baseband information is obtained by applying the mixed signal to the non-linear I-V characteristic curve. Other embodiments are disclosed.

  • Publication number: 20220166655
    Abstract: Aspects of the subject disclosure may include, for example, receiving a radio frequency (RF) signal having a carrier wave component that operates at a carrier frequency within a millimeter wave spectrum. The RF signal also includes an information component based on a phase shift keying (PSK) modulation of the carrier wave component. A local oscillator (LO) signal is obtained, which includes an LO frequency that approximates the carrier frequency. The received RF signal and the LO signal are combined without using signal multiplication to obtain a first combined output signal. The first combined output signal being detected via a non-linear energy detector to obtain a first detected signal. The first output signal includes information of the information component. Other embodiments are disclosed.

  • Publication number: 20220166458
    Abstract: Aspects of the subject disclosure may include, for example, generating multiple digital reference pulses synchronously to a master oscillator, selectively switching the multiple digital reference pulses, and providing the switched pulses to multiple radio modules operating within a millimeter wave spectrum. For each radio module, counting cycles of an adjustable LO output signal occurring between consecutive pulses of the switched digital reference pulses, determining a difference between the count value and a reference value, and adjusting the adjustable LO according to the difference. A resulting corrected LO signal is synchronized to the master oscillator. Other embodiments are disclosed.

  • Patent number: 11303347
    Abstract: Aspects of the subject disclosure may include, for example, receiving an RF signal having a carrier wave component operating at a carrier frequency within a millimeter wave spectrum and an information component based on a phase modulation of the carrier wave component. The received RF signal is divided into first and second signal portions that remain in phase with respect to each other. The first signal portion is delayed by one symbol period of the phase modulation and combined with the second signal portion to obtain a combined output signal. An in-phase portion of the combined output signal is detected via a non-linear energy detector, wherein an amplitude of the first detected signal corresponds to the in-phase portion of the received RF signal. The first combined output signal includes information of the information component. Other embodiments are disclosed.

  • Patent number: 11296742
    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.
