Abstract
Systems and methods are provided herein for implementing a hybrid communications network including both radar and radio communications devices. These systems and methods may advantageously include shared resource allocation protocols for automatically allocating communication resources for transmitting and/or receiving a signal using a device in the network based on one or more dimensions of separability for the signal selected from time-division, frequency-division, spatial-division and/or code-division multiplexing. Importantly, the resource allocation protocol may account for radar specific operational parameters of one or more radar devices in the network.
Claims20
A communications system for a hybrid communications network designed to support both radar and radio communications devices, the communications system including algorithms implementing a shared source allocation protocol shared by both radio and radar communications devices which, for both radar and radio devices joining the network, automatically allocates communication resources for transmitting and/or receiving a signal based on a dimensions of separability for the signal, the dimensions of separability selected from time-division, frequency-division, spatial-division and/or code-division multiplexing, wherein the resource allocation protocol accounts for both radar specific operational parameters and radio specific operational parameters of the communications network;
- wherein the resource allocation protocol is implemented by each device in the network including both radar and radio devices having a common medium access control (MAC);
- and
- wherein the resource allocation protocol is further implemented by each the network including both radar and radio devices having a common resource allocation manager (RAM) implementing resource allocation algorithms based on a pseudorandom hashing algorithm that awards communication resources to each device in the network resources based on preprogrammed allocation parameters and a current world view of other devices in the network.
