This paper describes the design process of Car Black Box system IC. As x by wire is introduced to the several part in vehicle, the demand of automotive semiconductors are increasing. Because it will be mandatory for every car to be equipped with Car Black Box, it is expected that many ICs for Car Black Box also will be integrated. Unlike general electronic(More)
This paper presents a simple diversity scheme by selecting the transmit antennas according to the feedback channel state information. Compare with the simple transmit diversity scheme using two transmit antennas and one receive antenna (STD/spl I.bar/2Tx1Rx), it obtains better performance of 1.5 dB and requires almost half radiated power.
