  • Signal constellation slicer
    Patent number: 6154502
    Abstract: Data represented by a received point which is not within a boundary of a signal constellation having a set of points is obtained by comparing the received point to less than all of the points on a boundary of the signal constellation. In an embodiment, the received point is compared to no more than two points on the boundary which have been predetermined to be the closest to the received point.

  • Use of RSSI indication for improved data transmission over amps network
    Patent number: 6073030
    Abstract: A method of using control channel information is provided to enhance data throughput of a cellular communication system. The cellular communication system includes a single system control unit coupled to a data pump, a cellular transceiver and a radio transceiver. A method of operating the cellular communication system includes the following steps: (a) detecting a control channel signal indicating that a channel interruption is to occur; (b) decoding the control channel signal; (c) sending the decoded control channel signal to the system control unit; (d) controlling the parameters of the adaptive components of the data pump so that the parameters remain at a converged state or are adjusted even during the channel interruption; (e) interrupting the channel; and (f) re-establishing the channel within a reduced retraining time period.

  • Data transmission over amps networks
    Patent number: 5911115
    Abstract: a modem that measures the received signal, characterizes the aptitude and phase distortion of the received signal across the bandwidth of the communication channel and pre-distorts the signal that is transmitted such that the introduced predistortion and the distortion in the channel cancel each other.
