An impulse radio communications system using one or more subcarriers to communicate information from an impulse radio transmitter to an impulse radio receiver. The impulse radio communication system is an ultrawide-band time domain system. The use of subcarriers provides impulse radio transmissions added channelization, smoothing and fidelity. Subcarriers of different frequencies or waveforms can be used to add channelization of impulse radio signals. Thus, an impulse radio link can communicate many independent channels simultaneously by employing different subcarriers for each channel. The impulse radio uses modulated subcarrier(s) for time positioning a periodic timing signal or a coded timing signal. Alternatively, the coded timing signal can be summed or mixed with the modulated subcarrier(s) and the resultant signal is used to time modulate the periodic timing signal. Direct digital modulation of data is another form of subcarrier modulation for impulse radio signals. Direct digital modulation can be used alone to time modulate the periodic timing signal or the direct digitally modulated the periodic timing signal can be further modulated with one or more modulated subcarrier signals. Linearization of a time modulator permits the impulse radio transmitter and receiver to generate time delays having the necessary accuracy for impulse radio communications.

The present invention relates to method, terminal device and network device for providing redundancy parameters for an automatic repeat request processing at a terminal device. At least one sequence of redundancy parameters is selected from a predetermined set of sequences and is signaled to the terminal device by using a strategy information indicating the selected parameter sequence. Thereby, the network operator is able to select the redundancy version strategy to be used by the terminal device, while little signaling is required between the network and the UE. Moreover, a flexible strategy can be provided where individual redundancy version strategies can be allocated to the connections.

Multiple streams from multiple circuit paths are Block-TDM (Block-Time-Division-Multiplexing) aggregated into a single stream that passes via a single path through processing circuitry capable of handling the aggregated signal. The cost of providing redundant processing circuitry is avoided. After processing in the single path, the resulting signal is Block-TDM de-aggregated to generate multiple streams. Each output stream is substantially the same as if its corresponding input stream had been processed in a separate path using separate processing circuitry. The path-sharing technique is usable to pass multiple streams from multiple radio receivers through one superior Delta-Sigma ADC (DSADC) as opposed to using multiple flat ADCs to process information from the multiple receivers. In one example, the DSADC can be used because the aggregation is Block-TDM-based and the de-aggregator involves a digital low pass filter. In another example, the de-aggregator involves a decoder and the aggregator involves a precoder.

The reagent can be prepared to yield a predetermined stoichiometric ratio of the functional groups on the scaffold such that the probe has a fixed stoichiometric ratio of the functional groups.

Video signals received on TV channels are recorded and reproduced with time-division compression and decompression to and from a storage medium to allow the video signals to be reproduced while the signals are being recorded.
