A novel and improved method for implementing a high-transmission-rate over-the-air interface is described. A transmit system provides an in-phase channel set and a quadrature-phase channel set. The in-phase channel set is used to provide a complete set of orthogonal medium rate control and traffic channels. The quadrature-phase channel set is used to provide a high-rate supplemental channel and an extended set of medium rate channels that are orthogonal to each other and the original medium rate channels. The high-rate supplemental channel is generated over a set of medium rate channels using a short channel code. The medium rate channel are generated using a set of long channel codes.

An apparatus that automatically adjusts the adaptation block size for a least-mean square (LMS) adaptive filter depending on the input signal-to-noise ratio (SNR) is disclosed. The apparatus monitors the instantaneous SNR and continually adjusts the block size to provide high noise immunity, thereby increasing the convergence speed of the filter and decreasing the asymptotic mean-square error. An exemplary embodiment of the present invention is presented in the context of acoustic echo cancellation, though it is noted that the adaptive filter of the present invention is useful in any environment in which the noise characteristics are subject to change.

A detector is used to sample of set of power measurements of a receive signal. The receive signal may comprise one or more signals from remote users as well as interference. A variance of the set of power measurements is also determined. The variance is compared to an overload threshold value. If the variance exceeds the overload threshold value, for some period of time, the system is declaraed to be operating at a potentially unstable point. In this state, future connection originations are denied.

A method and apparatus for transmitting voice and data in a code division multiple access (CDMA) wireless telecommunications system is described. In an exemplary embodiment of the invention, a base station transmits voice information at a voice transmit power and data at a data transmit power that is equal to a maximum transmit power minus the voice transmit power. In a preferred embodiment of the invention, each base station reports the voice transmit power to a base station controller in 20 ms intervals. The base station controller responds by calculating an available data transmit capacity, and by forwarding data to each base station equal to the available data transmit capacity. Each base station then transmits all voice data at the current voice transmit power, and data at the current data transmission power. If the amount of data received exceeds the capacity provided by the current data transmission power, some data is not transmitted. The base station then notifies the base station controller if data was not transmitted, and the base station controller attempts to retransmit the data at a later time.

An apparatus and method for providing communication of information between a truck tractor and trailer via existing truck wiring. At least one transmitter is located in each trailer for generating a unique identification signal representative of trailer identification information corresponding to the trailer in which the transmitter is located, modulating the identification signal, and providing the modulated identification on an existing truck power bus coupling the tractor and trailer. A receiver is located in the tractor for receiving each modulated identification signal on the power bus, demodulating each modulated identification signal and providing each demodulated identification signal to a mobile communications terminal located in the tractor for transmission to a central facility. The system may further include the transmission of trailer status or load status information by the transmitter to the receiver in a similar manner as the identification information.
