Latest Patents
Richard Walvis holds a patent for a "Method and system of channel analysis and carrier selection in OFDM and multi-carrier systems." This invention presents a novel method for channel estimation in OFDM systems. The embodiment of this invention is a block of new logic and modifications performed to other components of the system, which can be added to any existing OFDM receiver. It utilizes information available from other blocks found in the receiver. This logic improves the unit's error rate due to enhanced channel quality estimations. The improvement is made possible by using both channel noise data and channel signal data in the estimation process. This data undergoes a learning process over time and multiple data blocks for further enhancements in the quality of the estimate. Notably, this improvement can be achieved without direct communications with other remote units, although it could be utilized in a multi-node environment to enhance overall system performance.
