An adaptive MIMO communications system includes a multifunctional reconfigurable antenna with a selectively alterable effective physical antenna array configuration and radiation/polarization properties, which configuration and properties is a component in the optimization of the adaptive system parameters. The multifunctional reconfigurable antenna comprises a plurality of antenna components and a plurality of selectively controllable switches coupling selected ones of the plurality of antenna components together into a multifunctional reconfigurable subarray of antenna components. A processing unit coupled to the multifunctional reconfigurable antenna determines communication channel conditions for generating adaptive control signals to the plurality of selectively controllable switches to selectively apply a selected space-time coding protocol or a selected beam forming protocol together on the plurality of antenna components depending on channel conditions.
An improvement in an adaptive MIMO communications system comprising a multifunctional reconfigurable antenna array with a selectively alterable effective physical antenna array configuration and radiation/polarization properties, which configuration and properties is a component in the optimization of the adaptive system parameters.
An improvement in a method of operating an adaptive MIMO communications system comprising:
An improvement in a method of optimizing operation of an adaptive MIMO communications system comprising operating a plurality of multifunctional reconfigurable antennas to introduce an additional degree of freedom by treating the physical antenna array configuration and its radiation/polarization and frequency properties as adaptive system parameters.
An improvement in a method of operating an adaptive MIMO communications system comprising operating a plurality of multifunctional reconfigurable antennas according to a plurality of adaptive coding schemes to optimally respond to the changes in the propagation environment with rapidly changing multipath conditions in which reconfiguration of antenna properties and array configuration is dynamically combined with selection of the adaptive coding scheme to provide an optimal communication.
