摘要： First and second transmission links are established with a remote station. An information signal is encoded to provide an encoded information signal having more bits than the information signal. First and second transmission signals are provided wherein each transmission signal has bits selected from the encoded information signal. Each of the first and second transmission signals is transmitted to the remote station by way of a respective one of the first and second transmission links. The remote station receives and combines the first and second transmission signals transmitted by the remote station to provide a combined encoded signal. The combined encoded signal is decoded by the remote station to provide the information signal. The first and second transmission links can be formed between the remote station and a single base station or between the remote station and two separate base stations.

摘要： A means for reducing the power consumption of the transmitter by storing the recent history of the transmitted data using a string of gates with taps from the string taken at points determined by the propagation delay of each gate and controlling driving transistors as a function of comparison of that history with input data so that, either the signal is driven into the transmission line at full strength, or at a level near the minimum needed to retain the state in the receiver. The advantage of the invention is that the line capacitance decays through the terminating resistors or discharge transistors, such that when the next state change is needed, then line has less stored energy needing to be discharged.

摘要： Useful information taking the form of an analog or digital voltage is communicated between a transmitter and a receiver using UWB signals. The transmitter includes a subcarrier modulator, a high frequency oscillator and a transmission antenna and the receiver includes a reception antenna and an amplifier and a demodulator for discriminating the useful information in a signal received at the reception antenna. On transmission, the method generates a narrow frequency band high frequency carrier, modulates the high frequency carrier using a subcarrier with a modulation index at least equal to 10, and modulates the subcarrier using the useful information. On reception, the method demodulates the carrier to extract therefrom the subcarrier and demodulates the subcarrier to extract therefrom the useful information.
