Wireless Network Circuit
Wireless circuit technology
Recently, many electronic equipments with wireless communication function are used everywhere and the importance of wireless technology is rapidly increasing. It is important to improve mobile network system which became more useful by the widely spread smart-phones. Building of reliable wireless network against major disasters is also important. Generally, the demand for wireless network and its equipments are following four points, anytime anywhere, faster communication speed, lower price and longer buttery life.
To respond to these demands, we are making effort to realize high-performance, low power consumption and high flexibility wireless communication system via the research of RF analog circuit, digital circuit and software technology for the PHY layer implementation.
We are developing digital-analog mixed circuit technology for lower power consumption, smaller size, and wide-band wireless base stations and handsets. These technology enables the reduction of OPEX such as electricity expense and site rental. Our research topics include highly efficient RF power amplifiers for wireless infrastructures , reconfigurable analog circuits for software-defined-radio system, and millimeter wave circuits for giga-bit wireless communications.
We are also developing digital baseband circuits for the base stations and terminals which are able to switch some conventional and newly developed wireless standards by rewriting its software. From a part of the developments, we are developing a baseband platform which employs heterogeneous multiple-core architecture, and we are researching special purpose wireless signal processing engine architecture, and its programming method.
We will continuously make effort to improve its processing performance and its program development efficiency for the expanding wireless network world. We also challenge to the emerging wireless technologies such as the M2M.
