摘要: A modulation system can switch between two modulation modes. In order to comply with limits on peak power in spectral bands outside the RF operating one the transmitter is required to ramp down to a condition of minimal power. To avoid fixed ramping and trailing bits, the transmitting signal is subjected to FIR filtering. The two FIR filters are primed with a sequence using a parallel input mode before serially entering the information data.

摘要: A device for deriving a predistorted signal for provision to a non-linear element comprising memory for storing a plurality of data samples that define a segmented approximation of distortion curve characteristics for the non-linear element where the plurality of data samples define the segment boundaries and a predistortion module for determining within which segment of a plurality of segments a predistortion input signal would provide an output signal substantially equal to an idealized output signal and deriving a predistortion signal based upon the segment boundaries.

摘要: This invention relates to a novel design of ergonomic tool box. More particularly, this invention relates to a novel construction of ergonomic tool box which has upper and lower handles for ease of carrying, and an indented side which enables the ergonomic tool box to be carried closer to the vertical center of gravity of the carrier, thereby reducing strain on the carrier. An ergonomic tool box comprising: (a) an elongated hollow base with one of the sides of the base being indented inwardly towards the interior of the hollow base; (b) a handle disposed upwardly from the hollow base; and (c) at least one support for the handle extending upwardly between the base and the handle.
