Abstract: A power controller apparatus for use in a mobile radio system wherein, when an error is detected in a transmitted signal, the transmit power is increased and when no error is detected, the transmit power is reduced by a smaller amount thus maintaining a constant bit error rate related to the ratio of the up and down step sizes. The power controller also contains a comparator for comparing the data which is transmitted with the data which has been transmitted to a station and retransmitted back.

Abstract: A wireless magnetic resonance imaging scanner has one or more local coils, a microwave antenna array, and a local oscillator, and an upconverter. The local oscillator signal from the local oscillator is transmitted from the microwave antenna array to illuminate the local coils. The local coils generate magnetic resonance signals at a first frequency and the magnetic resonance signals at the first frequency are upconverted in the upconverter to microwave frequencies. The local oscillator operates at a frequency within an unlicensed band, chosen such that desired sidebands for reception of the upconverted local coil magnetic resonance signals fall outside the unlicensed band.

Abstract: An upconverter has a two port parametric amplifier that has a first port to receive an input signal to be amplified and upconverted and a second port to receive a local oscillator signal and to output the amplified, upconverted signal at upper and lower sideband frequencies. The upconverter further has an antenna coupled to the second port to receive the local oscillator signal and transmit the amplified, upconverted signal at upper and lower sideband frequencies and a low noise amplifier at the first port of the parametric amplifier, which is powered by the local oscillator signal.

Abstract: A method of transmission comprises receiving at a first destination, a transmission from a first source; determining from the transmission from the first source, the maximum permitted additional interference subject to which the first destination can still communicate; sending an acknowledgement of the transmission and including in the acknowledgement an indication of the determined maximum permitted additional interference. A second source determines whether it has received the transmission from the first source, or the acknowledgement from the first destination, at a power level lower than that of the maximum permitted additional interference given in the indication; and if so, the second source sends a transmission to a second destination, which at least partially overlaps in time, communication between the first source and first destination.

Abstract: The apparatus transmits in a first zone, for example, an aircraft, a masking signal which masks transmissions from a second zone outside of the first. By doing this a mobile cellular telephone is inhibited from connecting or attempting to connect to base-stations on the ground. A hole in the masking signal spectrum may be provided to enable connection to a base-station within the aircraft. Alternatively, a base-station within the aircraft may be arranged to transmit at a power level greater than the masking signal.

Abstract: The apparatus receives an input signal via an antenna or cable 2, and the signal is applied to a frequency converter 4. Frequency converter generates complex I Q baseband signals which are applied to a respective correlator comprising a multiplier 6 and an accumulator 12 in respect of the inphase signal and the multiplier 8 and an accumulator 14 in respect of the quadrature phase signal. The output of the correlators are subjected to a modulus squaring function which comprises multipliers 16, 18 and an adder 20. The output of the adder 20 is applied to a store 22, and the inputs and outputs to the store are arranged to be added together in an adder 24, the output of which is compared in a comparator 26. The correlators and store are controlled by a controller 28 which is arranged to control the setting and resetting of the accumulators 12 and 14. For a fixed interval of time a local code generator is held constant, the output of which is applied to an input of the multiplier 6, 8, and at the start of the interval the accumulators 12, 14 are reset to zero and allowed to accumulate. At the end of the period the comparison is performed and thereafter the codes generated are shifted by one chip and the accumulators 12, 14 are set to zero and the output of the adder 20 is clocked into the storage means 22. This process is repeated until such time as the threshold values exceeded as determined by the comparator 26.

Abstract: Modulation schemes requiting fully coherent demodulation usually include some form of known transmission or pilot transmission to resolve the phase ambiguity which would be inevitable in any form of demodulation which relies on the data transmission allowed for demodulation. When the transmission of phase shift keying information is used without any pilot component and use of decision directed carrier recovery for demodulation is supplied, then error control coding may be used to resolve the inherent phase ambiguities. The source data is augmented with a suitable checksum, i.e. one that does not show correct data for all bits inverted prior to protection with a forward error correction code and modulation. The demodulated data is error corrected and the checksum tried. If this checks out then the data is accepted as correct. Otherwise the demodulated data is inverted and the process repeated. If this fails, blocks of demodulated data may be inverted around points corresponding to troughs in the energy of the decision derived reference. The technique allows coherent demodulation of phase shift keying without any pilot transmission resulting in very good signal to noise ratio performance.

Abstract translation: 要求完全相干解调的调制方案通常包括某种形式的已知传输或导频传输，以解决在依赖于允许解调的数据传输的任何形式的解调中不可避免的相位歧义。 当使用没有任何导频分量的相移键控信息的传输并且提供用于解调的决策导向载波恢复的使用时，可以使用误差控制编码来解决固有的相位模糊度。 源数据用适当的校验和进行增强，即对于在使用前向纠错码和调制进行保护之前，所有反转的位都不显示正确的数据。 解调后的数据被纠正，校验和尝试。 如果这样做，那么数据被接受为正确的。 否则解调的数据被反转，并且重复该过程。 如果这失败，解调数据块可以在与决定导出参考的能量中的谷对应的点周围反转。 该技术允许相移键控的相干解调，而无需任何导频传输，导致非常好的信噪比性能。
