Summary:
UCLA researchers in the department of Electrical Engineering have developed a universal multiple-input multiple-output (MIMO) decoder that incorporates all available decoding algorithms necessary for any wireless standard.
Background:
MIMO has become a key technology for wireless communication, but it is believed that the demands put on MIMO systems will change with emerging technology. An example of this is the integration of emerging technologies, such as Worldwide Interoperability for Microwave Access (WiMAX), into systems that already operate on other standards (e.g. cellular, WiFi). Due to this integration, there will be a great need for systems that can operate across standards, support standards with multiple modes, and decoders that can switch between different decoding algorithms. Using the current method of MIMO decoder design, however, such systems will be prohibitively expensive.
Innovation:
The inventors have proposed a universal MIMO decoder that contains all core operations necessary to implement any decoding algorithm. Thus, this MIMO accelerator results in a much cheaper decoder that works with next-generation wireless technology that would not be otherwise attainable. The setup also allows for reprogramming to new algorithms and resource trade-off in real time.
