Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for reducing transmitter peak power requirements with orthogonal code noise shaping. SOLUTION: A method and apparatus for reducing peak transmitter power includes providing a set of orthogonal communication codes for a telecommunications system that includes a set of active user codes and a set of inactive user codes (1404). A communication signal is generated from the set of active user codes (1406). The peak-to-average power ratio of the communication signal is reduced by performing a peak cancellation function on the communication signal that minimizes energy distribution of at least one of the set of active user codes and the set of inactive user codes (1410).

Abstract: A communication system (100) transitions from a high velocity mode of operation to a non-high velocity mode of operation based on a movement of a mobile station (106). When the communication system is in a high velocity mo de of operation, the communication system promotes pilots from a High Velocity Neighbor Set of the mobile station or a controller (116). When the communication system is in a non-high velocity mode of operation, the communication system promotes pilots from a Neighbor Set of the mobile stati on or the controller. The communication system may further include a high velocity repeater (104) that, when co-located with the mobile station, is capable of providing a communication link between the mobile station and a radio access network (114) servicing the mobile station.

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: 2053897 9015451 PCTABScor01 A microstrip capacitively-compensated directional coupler (100) with improved directivity and decreased coupling length. The directional coupler (100) of the invention includes a primary transmission line (102), having a first port (126) and a second port (128) and a secondary transmission line (104) electromagnetically coupled to the first line. The secondary transmission line has a third port (130) and a fourth port (132). The invention also calls for a first reactive coupling network (138) disposed between the first port (126) and the third port (130), and a second reactive coupling network (140), disposed between the second port (128) and the fourth port (132). Those reactive couplings improve the directivity of the coupler (100) and foreshorten its coupling length. The invention also calls for a phase-shifting line (210) for shifting the phase of the coupled signal. The phase-shifting line (210) further foreshortens the required coupling length for the coupler.
