Abstract: A master station communicates with the main network, whilst a set of mobile or fixed sub stations of voice or data users share the channel using time division multiplexing. The number of time division channels available depends on the quality of the transmission links, power and modulation index. The rate of errors is detected to maintain a specified condition of operation. When all available channels are occupied a busy signal is transmitted by the master station. The effect of multiplexing on the sub-links gives apparent simultaneous bidirectional transmission.

Abstract: A modulator for a modem, said modulator being adapted to convert a bit stream, wherein each given number of successive bits defines a symbol, into a phase modulated intermediate frequency (IF) signal, the symbols in the modulator section being phase modulated DPSK conversion. The phase modulated symbols are then digitally filtered to provide a filtered signal comprising time shared, digital in-phase and quadrature phase components that, when converted into an analog signal, provides a modulation signal of a frequency that is centered about a predetermined frequency and deviates therefrom in accordance with the value of the phase modulated symbol. The filtered signal, after being converted to an analog signal is then filtered and passed to a mixer for up conversion to an IF signal.

Abstract: A system for wireless transmission of multiple information signals between a base station and a number of subscriber stations by the use of digital time allocation circuits. The subscriber stations can be stationary or mobile. The number of time allocation circuits is determined by the transmission quality of the signals. The base station is connected to an external information network which can be analogue and/or digital. The information signals have been selected from the group consisting of voice, data, fax, video, computer and instrumentation signals. The modulation level of the signals and the energy which is supplied to the system are set in accordance with the signal error detection in the system. The system has been provided with spatial dispersion by the use of a number of antennas, which are arranged selectively at a distance from each other to achieve relatively high signal reception notwithstanding signal fading. The base station operates on a number of pairs of RF channels. The operation of each pair of channels is assisted by the combination of a transmitter channel circuit for handling a given number of information signals, which are received simultaneously over a telephone company's trunk lines for simultaneous transmission to various subscriber stations over a given RF channel, and a receiver channel circuit for handling a number of signals which are received simultaneously over a given RF channel from various subscriber stations to create information signals for transmission over the trunk lines.
