1. A device for providing enhanced diversity reception and/or cosite cancellation, the device comprising:
- a first antenna for transmitting and receiving signals;
a circulator for connecting a transmit chain to the first antenna and for connecting the first antenna to a first input of a combiner;
a second antenna for receiving signals;
adjusting circuitry for connecting the second antenna to a second input of the combiner; and
a first detector for detecting an output of the combiner and providing the detected signal to a receive chain.

Abstract
Devices and methods for providing enhanced diversity reception and cosite cancellation are disclosed. According to one aspect, the subject matter described herein includes a device for providing enhanced diversity reception and cosite cancellation. The device includes a transmit chain connected to a circulator further connected to first antenna and to a combiner. The combiner is connected to anti-cosite circuitry and to first detector. The anti-cosite circuitry is further connected to a secondary antenna. The first detector is further connected to a receive chain.
