Abstract: In a hybrid matrix amplifier array (100), a configurable digital transform matrix (116) is initialize with a matrix of transform coefficients. A plurality of digital input signals (M1-M4) are received at inputs of the configurable digital transform matrix (116). The plurality of digital input signals are transformed to produce a plurality of transform digital signals (A1-A4) using the matrix of transform coefficients. The plurality of transform digital signals are converted to a plurality of transformed analoged signals (206) to produce a plurality of transformed analog signals. The transformed analog signals are amplified (104, 208) to produce amplified transformed signals. Finally, the amplified transformed signals are inverse transformed (102, 210) to produce output signals that correspond to a respective digital input signal (M1-M4). Upon sensing a failure in an amplifier array (104,126) a controller (128) recalls matrix transform coefficients from a memory (130) and write and reconfigures the digital transform matrix (116) to minimize the effects of the amplifier failure at the hybrid matrix amplifier outputs (132).

Abstract: A multiple access digital up converter/modulator includes selectors (1606, 1608) having inputs (1602, 1604) and outputs coupled to first and second interpolating filters (1610, 1626). The output of the first interpolating filter is selectively coupled to a first mixer (1612) and a first adder (1622), the first adder also receiving a first phase value, and the output is coupled to a first phase accumulator (1616) the output of which is coupled to a first sinusoid generator (1614) and selectively coupled to a second sinusoid generator (1630). The outputs of each of the first and second mixers are selectively coupled to an output adder (1634) and to inputs of the first and second mixers. The output of the second interpolating filter (1626) is selectively coupled to a second mixer (1628) and a second adder (1638), which also receives a second phase value and the output of which is coupled to a second phase accumulator (1640) the output of which is selectively coupled to the second sinusoid generator.

Abstract: A multi-channel digital transceiver (400) receives uplink radio frequency signals and converts these signals to digital intermediate frequency signals. Digital signal processing, including a digital converter module (426), is employed to select digital intermediate frequency signals received at a plurality of antennas (412) and to convert these signals to baseband signals. The baseband signals are processed to recover a communication channel therefrom. Downlink baseband signals are also processed and digital signal processing within the digital converter module (426) up converters and modulates the downlink baseband signals to digital intermediate frequency signals. The digital intermediate frequency signals are converted to analog radio frequency signals, amplified and radiated from transmit antennas (420).
