Cluster based multiplexing of radar and communication signals in mm-wave band

1. A method for cluster-based multiplexing of radar and communication signals in an mm-wave band, the method comprising:

transmitting the radar and communication signals independently through a common channel via different transmitters;

multi-beam forming the transmitted radar and communication signals in the mm-wave by digital beam forming and spatial multiplexing;

performing channel modeling and estimation by the steps of:

sending the radar and communication signals over a common time frequency resource for estimation, the sent radar and communication signals being angularly separated such that each beam is transmitted over a different angle;

transmitting communication beams by a transmitter so as to start a connection;

receiving the transmitted communication beams at specific angles;

applying a channel equation to the received communication beams;

identifying unused angles by the transmitter; and

informing the transmitter with a feedback so as to transmit sensing beams over the unused angles;

transmitting multiple beams;

encountering each of the multiple beams with different scatterers so as to reflect at an angle;

using the different reflected multiple beams so as to multiplex the radar and communication signals into the common channel; and

receiving multiple clusters in a receiver in order to perform the step of performing channel modeling and estimation.

2. The method of claim 1 , wherein the multiple clusters are orthogonal.

3. The method of claim 1 , wherein the multiple clusters are partially orthogonal.
