摘要： Apparatus for encoding a plurality of received radio frequency (RF) analog signals. The apparatus includes a plurality of pseudo-noise (PN) encoders for performing analog signal spreading and down-conversion. Each PN encoder is configured to encode a respective received RF analog signal using a respective one of a plurality of mutually orthogonal PN complex codes and to output a respective PN-encoded analog signal. The apparatus also includes a PN complex code source configured to provide the mutually orthogonal PN complex codes to the plurality of PN encoders. The PN complex code source includes a code generator for generating multiple mutually orthogonal PN codes, and a complex modulator for modulating the mutually orthogonal PN codes.

摘要： A variable capacitance and control system used in a compensative manner to improve efficiency in power amplifier arrangements arranged to receive a power input which is voltage-modulated responsive to at least one control signal representative of the data signal. Also included are methods and software for controlling said power amplifier arrangements including the variable capacitance and control system. The data input to the power amplifier is pre-distorted and the resulting power amplification is substantially linear. The arrangement may be used in wireless base station transmitters, for example. Improved data transmission services are also provided which make use of such power amplifiers.

摘要： This invention relates to high power linear amplifiers. A high power linear amplifier is disclosed for communications such as CDMA communication systems. Linear amplifiers as used in communication systems exhibit a linear characteristic where the amplifiers output power increases relative to an input power. After a certain input level, known as a gain saturation point, the amplifier then exhibits non-linear characteristics; the output power increases relatively little with respect to power input. This non-linear region is also known as the saturation region or the gain compression region. In accordance with the invention, there is provided a power amplifier comprising a power amplifier, a feedback circuit and a control element;wherein the feedback circuit receives a sample of the input signal delayed in time and employs phase and amplitude components of both the input signal delayed in time and a feedback signal derived from the output of the power amplifier to drive a control element, which control element determines the signal input to the amplifier whereby the power amplifier can produce an improved linear output.
