  • Patent number: 6185202
    Abstract: In order to allow a flexible allocation of transmission capacities in a radio transmission system, without disrupting or interrupting existing radio connections, a control device is provided which, in the event of a change in the transmission channels, adjusts one or more of the transmission parameters in a central station and in affected subscriber stations in such a way that the bandwidth of the available radio channel is optimally utilized. For this purpose, the modems present in the central station and in the subscriber stations are equipped with two transmitted signal paths and two paths and two received signal paths, only one of received signal paths (ENC1, ENC2, IF1, IF2, MOD1, MOD2, DEM1, DEM2, DF1, DF2, DEC1, DEC2), only one of which is activated in each case for a signal transmission. The outputs of the transmitted signal paths and the inputs of the received signal paths are equipped with frequency splitters.

  • Patent number: 5530471
    Abstract: A distribution system, useful with radio and television distribution, for distributing a signal having a plurality of channels includes a central station. The central station produces a first frequency division multiplexed signal in which signals from a plurality of channels or channel groups are frequency-converted and combined, and introduces the first frequency division multiplexed signal into transmission media of the distribution system. The first frequency division multiplexed signal may include occupied channels, freely selectable occupied channels, and free channels. A plurality of further stations receive the first frequency division multiplexed signal from the central station and process it with signals of a plurality of further channels to produce a second frequency division multiplexed signal. The signals of the plurality of further channels may be put in free channels, or used to replace signals in freely selectable occupied channels of the first frequency division multiplexed signal.

  • Patent number: 5461612
    Abstract: A drop-and-add multiplexer for receiving an incoming FDM signal with a plurality of channels, for receiving signals of additional channels, and for outputting an outgoing FDM signal. The multiplexer includes at least one single channel filter for receiving an incoming FDM signal, filtering the incoming FDM signal by blocking a selected channel frequency, and outputting a filtered FDM signal. At least one interpolating digital frequency converter receives another channel signal which is not in the incoming FDM signal, converts the other channel signal into a channel frequency which has been blocked by the at least one single channel filter or was an empty channel frequency in the incoming FDM signal, and outputs a converted other channel signal.

  • Patent number: 5177700
    Abstract: A non-recursive half-band filter having a filter length N and complex coefficients for receiving either a real input signal s(kT) or a complex input signal s(2kT) and for processing and converting the received input signals into either a complex output signal s(2kT) or a real output signal s(kT) wherein the complex coefficients operate at a function of h(l) where l=-(N-1)/2 to (N-1)/2 to (N-1)/2 and the filter length N is odd. As a result it is possible to convert a real input signal into a complex output signal, by modulating its pulse response to a complex carrier of the frequency equal to 1/4 or 3/4 of the sampling frequency, where the null phase of this frequency is an integer multiple of .pi./2. It is also possible to convert a complex input signal into a real output signal, by modulating its pulse frequency to the complex carrier of a frequency signal to the input sampling frequency or half thereof, where the null phase of this frequency is an integer multiple of .pi./2.

  • Patent number: 4389616
    Abstract: A method for digitally regulating the residual carrier phase error in receivers of digital data transmission systems. A comparator compares the sampled data signal or value of the carrier demodulated input signal to the receiver with the estimated value for each associated sampling time or moment as provided by a decider, to determine the deviation dk which is a measure for the phase difference between the sampled value and the associated estimated value. This deviation dk is filtered in a digital loop filter, including a proportional branch and an integration branch, and a regulating value for the demodulated input signal is obtained from a subsequently connected accumulator. A non-linear limitation on the deviation dk is included in the integration branch of the digital loop filter.
