RADIO TRANSCEIVER WITH IMPROVED RADAR DETECTION

摘要

A radar detector is used with a radio link, the radio link characterized by high duty factor operation of a radio transmitter. The radar detector is located a sufficient distance from the radio transmitter that the radar detector is not overwhelmed by the radio transmission signal in that channel and can detect sufficiently low level radar signals to ascertain potential radio interference at the radar from said radio transmitter. The results of the radar detection are communicated to the transmitter in a way that impacts the transmitter's use of the sensed channel. This communication can occur reactively when a radar detection is achieved (the absence of which indicates no radar has been detected) and/or can be a periodic or event-driven indication that the channel is available for operation (the information expiring if the result is not refreshed).

主权项

1. A wireless communications system comprising:
a first transceiver, wherein the first transceiver comprises a first transmitter, a first receiver, and a first radar detector, and wherein the first transmitter transmits on a first transmit channel; a second transceiver, wherein the second transceiver comprises a second transmitter and a second receiver, and wherein the second transmitter transmits on a second transmit channel; wherein the first receiver receives from the second transmitter on the second transmit channel and the second receiver receives from the first transmitter on the first transmit channel; wherein the first transmit channel is within a first transmit frequency band and the second transmit channel is within a second transmit frequency band; wherein the first radar detector is configured to detect radars within a first radar detection frequency range that includes at least part of the second transmit frequency band; wherein the first radar detector is configured to detect radars within at least a first time period, the first time period comprising at least a period of time when the first transmitter and the second transmitter both transmit coincident in time; wherein the first radar detector communicates at least a first radar detection result via the first transmitter to the second receiver; and wherein the first radar detection result is an input to a controller associated with the second transmitter.
