20140287699 | RF FRONT-END MODULE - An RF front-end module includes a transmitting/receiving terminal, a control unit, a first transmitting block and a second transmitting block. The first transmitting block and the second transmitting block connect the transmitting/receiving terminal and the control unit. The control unit controls on or off status of the first transmitting block and the second transmitting block. Thus, the first transmitting block and the second transmitting block can send a signal to the transmitting/receiving terminal directly without pass through any switch unit, avoiding extra signal loss on switch unit. | 09-25-2014 |
20140358532 | METHOD AND SYSTEM FOR ACOUSTIC CHANNEL INFORMATION DETECTION - A method or a system for acoustic channel information detection includes at least one speaker and at least one microphone within an environment. The microphone receives a CDMA modulated audio training signal from the speaker via a plurality of acoustic channels within the environment, wherein the CDMA modulated audio training signal is a pre-known CDMA modulated audio training signal, and comprises a data signal, a spreading code and/or a continuous frequency code. Thus, the microphone is able to estimate the acoustic channel information including frequency dependence according to the received CDMA modulated audio training signal and the pre-known CDMA modulated audio training signal. | 12-04-2014 |
