摘要： Systems and methods are provided for searching for analog data, including hand writing, facial expressions and voice data. With respect to analog writing, a device records and stores analog writing, including time, pressure and position as a writing tool moves on a touch screen device. A search term that includes time, pressure and position data, is received. The search term is compared with the time, pressure and position stored on the device. If they are similar, then the stored analog writing is displayed. In other example embodiments, facial expressions and voice data can be used as search terms to respectively search for stored facial expressions and voice data.

摘要： A method, computer program, device and system are provided for determining channel state information for use in a wireless communications network. The channel state information includes a rank indicator (RI), precoding matrix index (PMI) and channel quality indicator (CQI). The RI, PMI or CQI can be determined based on channel covariance estimation and the Taylor series approximation of its inverse. Further, the RI and PMI can be determined separately.
