摘要： The present invention relates to a polar modulation apparatus and method, in which an in-phase and a quadrature-phase signal are processed in the analog domain to generate an analog signal corresponding to a derivative of a phase component of said polar- modulated signal. The analog signal is then input to a control input of a controlled oscillator (40). As an example, the processing may be based on a differentiate - and - multiply algorithm in the analog domain. Thereby, phase and envelope signals are generated in the analog domain and bandwidth enlargement due to the processing of the polar signals and corresponding aliasing can be prevented to obtain a highly accurate polar-modulated output signal.

摘要： A signal receiver for use in a 60 GHz wireless area network, in which the received RF signal band (100) is converted to a plurality of intermediate frequency (IF) sub- bands (104) and then processing (LPF, AGC, ADC) in the analogue domain of the sub-bands (104) is performed in parallel. As a result, the design requirements of the analogue components are significantly relaxed and it is possible to perform gain control in respect of each sub-band (104), which improves the quality of the received signal.

摘要： Devices (1) for exchanging ultra wide band signals comprise frequency translating stages (20,30) for frequency translating signals and oscillating stages (40) for supplying main inphase / quadrature oscillation signals to the frequency translating stages (20,30). By providing the oscillating stages (40) with polyphase filters (43,44) for reducing harmonics in oscillation signals, the main oscillation signals will be sufficiently clean. The oscillating stages (40) comprise mixers (46) for converting first inphase / quadrature oscillation signals and second inphase / quadrature oscillation signals into the main oscillation signals. The polyphase filters (43,44) may be located before and after the mixers (46). Frequency selectors (45) replace prior art multiplexers located after the mixers (46). Such frequency selectors (45) comprise multiplexers (126,127) for supplying the second inphase / quadrature oscillation signals, with a combination of these second oscillation signals corresponding with a positive frequency, a negative frequency or a zero frequency, and comprise coders (125) for controlling the multiplexers (126,127).

摘要： Telecommunication systems comprising transmitting units (1) and receiving units (11), with units (1 resp. 11) comprising parallel chains (2-4 resp. 12-14) coupled to processing parts (5 resp. 15), have enhanced data rates / channel capacities, under the assumption that the noise in the chains (2-4 resp. 12-14) is uncorrelated. Correlated noise from external noise sources decreases said rates / capacities. By coupling said chains (2-4 resp. 12-14) to said processing parts (5 resp. 15) via switches (6 resp. 16) for uncorrelating correlated noise in said chains (2-4 resp. 12-14), any correlated noise present in chains (2-4 resp. 12-14) is made uncorrelated. Said switch (30,50,70) (over/sub)samples chain signals, and is further coupled to said processing part (32,52,72) for controlling purposes to switch randomly or programmedly, with said processing part (32,52,72) and said switch (30,50,70) operating synchronically. Said switch (30,50,70) comprises a (de)multiplexer, with a chain comprising at least an antenna (21,22,41,42,61,62) and possibly an amplifier (25,26,43,44) and a mixer (27,28) coupled via said switch (30,50,70) to said processing part (32,52,72) comprising at least a filter (37,57,77), a converter (38,58,78) and a processor (39,59,79) and possibly said mixer (56,76) and said amplifier (75).

摘要： A frequency-hopping arrangement comprises a basic-frequency branch (DIVl), an offset-frequency branch (DIV2, DIV3, SCC), and a controllable frequency converter (SBM, FSC). The basic-frequency branch (DIVl) receives an oscillator signal (OS) having an oscillator-signal frequency (7920MHz). The basic-frequency branch has a frequency-division factor (/2) so as to provide a basic-frequency signal (BF) having a basic frequency (+3960MHz) that is the oscillator-signal frequency divided by the frequency- division factor. The offset-frequency branch (DIV2, DIV3, SCC) receives the same oscillator signal (OS). The offset-frequency branch has a different frequency-division factor (/3, /5) so as to provide an offset-frequency signal (OF) having an offset frequency (+528MHz) that is the oscillator-signal frequency divided by the different frequency-division factor. The controllable frequency converter (SBM, FSC) provides a frequency-hopping signal (FHS) having a frequency (cl*+3960 + c2*+528 MHz) that is a linear combination of the basic frequency and the offset frequency with at least one coefficient (c2) that varies as a function of a hopping-control signal (HCS).
