GRUNDIG 1020 WLAN DRIVER

More particularly, first, the input signal is under-sampled. The interfaces , , and include transmitters , , and respectively. Also, any combination of these networks may be coupled together, as illustrated in FIG. Control signal triggers on the rising pulse edge of the master clock signal , and control signal triggers on the falling pulse edge of the master clock signal The selection of the clock frequency is determined by choosing a sub-harmonic of the carrier frequency.

Likewise, the baseband signal is received at the source of the FET and is shunted to grounding according to the control signalto produce the harmonically rich signal As a result, the architecture of the UDF module is friendly to integrated circuit design techniques and processes.

Qlan charge transferred during a pulse is referred to herein as an under-sample.

Grundiv number of redundant spectrums a - n generated by generator is arbitrary and unlimited, similar to spectrums a - n discussed above. An example unified down-conversion and filtering module is illustrated in FIG.

For example, and without limitation, the UDF module can be designed with a filter center frequency k on the order of MHZ, and a filter bandwidth on the order of 50 KHz. Each image carries the I baseband information and the Q baseband information from the corresponding images andrespectively, without substantially increasing the frequency bandwidth occupied by each image In an embodiment, fourth UFD module comprises a fourth storage modulea fourth UFT moduleand a fourth voltage reference Please check the delivery terms and expenses before ordering online.

This allows the capacitor to charge to VI tsuch that node is at VI t.

In one embodiment, communications medium is an over-the-air link and medium interface module is an antenna. These and other applications of the UFT module are described below. More specifically, delays a and b phase shift the grunndig signals and for the Q channel modulator b relative to those of the I channel modulator a. First oscillator and second oscillator generate a first oscillating signal grubdig second oscillating signalrespectively.

The optional filter can be used to select the harmonic image of interest for transmission. The transmitter up-converts the processed I and Q signals, and combines the grunidg I and Q signals.

At the destination, the redundant spectrums are isolated from each other so grundiv the baseband signal can be recovered even if one or more of the redundant spectrums grundib corrupted by a jamming signal.

First, second, third, and fourth pulse generators,and may be implemented in circuit logic, hardware, software, or any combination thereof, as would be known by persons skilled in the relevant art s. The interface includes a transmitter and a receiver First stage modulator modulates first oscillating signal with modulating baseband signalresulting in modulated signal The Ex-OR function combines both signals by performing a modulo-2 addition of each information bit with each Barker bit or chip.

As indicated by the example of FIG.

Signal is split by a 90 degree splitter to produce an I signal A and Q signal B that are preferably 90 degrees apart in ggrundig. This is because the under-sampling pulses occur at different phases of subsequent cycles of input signal The present invention is directed to systems and methods of universal frequency down-conversion, and applications of same.

The NAV is kept current through duration values that are transmitted in all frames. The UDF module performs at least frequency translation and frequency selectivity. The spreading and despreading of narrowband to wideband signal is commonly referred to as processing gain and is measured in decibels dB.

As noted above, the train of pulses i. Voltage biases the UFT grubdig a and a in the I channel modulator a. Thus previously described benefits of the present invention are obtained in wireless modems, WLANs, etc. The UDF module performs the frequency translation operation and the frequency selectivity operation in an integrated, unified manner as described above, and as further described below.

Matched filter principle and energy transfer are further described in the above referenced applications, such as U. Also, the UDF module does not require that tight tolerances be maintained on the values of its individual components, i.

In a preferred embodiment, when present, second filter comprises a second resistora second filter capacitorand a second filter voltage reference Means of delivery all offers.

This is depicted, for example, in FIGS.
