摘要： The invention discloses a method for wireless terminal dynamically switching window in a wireless LAN environment. The wireless LAN comprises several access points and stations which establish wireless communication connections with the access points. The stations can switch the current access window by scanning. The method characterizes in that including following steps: giving the switching window an initial value through the stations; the stations judge if there is another access point of which the signal quality is greater than that of the current access window through scanning wireless channels; if so, further judge if the stations are in a frequently handoff status, if so, the handoff judging result is not allowed to switch window; if not, the handoff judging result is allowed to switch window. The present invention can adaptively adjust the stations' switch windows according to the stations' handoff status and frequently handoff status. On one hand, the invention avoids the occurring of frequently handoff by changing the handoff conditions of the stations, increasing the access efficiency of the stations which is in the handoff status and in a wireless LAN environment, while maintaining the sensitivity of the stations which is in the handoff status, ensuring the quality of the wireless links between the stations and the access points.

摘要： An apparatus comprising a programmable frequency device adapted to generate a reference clock selected from a set of distinct frequency clocks, wherein the programmable frequency device is further adapted to maintain the same temporal relationship of the triggering edges of the reference clock when switching between the distinct frequency clocks. The apparatus further comprises a phase locked loop (PLL), such as a digital PLL (DPLL), that uses the selected reference clock to establish a predetermined phase relationship between an input signal and an output signal. By maintaining substantially the same temporal relationship of the reference clock when switching between distinct frequency clocks, the continual and effective operation of the phase locked loop (PLL) is not significantly disturbed while changing the reference clock. This may be used to control the power consumption of the apparatus.

摘要： A circuit receives a first signal (for example, a baseband signal) and mixes it with a local oscillator (LO) signal, and outputs a second signal (for example, an RFOUT signal). The circuit includes multiple identical Mixer and Frequency Divider Pair (MFDP) circuits. Each MFDP can be enabled separately. Each MFDP includes a mixer and a frequency divider that provides the mixer with a local version of the LO signal. The MFDP outputs are coupled together so that the output power of the second signal (RFOUT) is the combined output powers of the various MFDPs. By controlling the number of enabled MFDPs, the output power of the second signal is controlled. Because the MFDPs all have identical layouts, accuracy of output power step size is improved. Because LO signal power within the circuit automatically changes in proportion to the number of enabled MFDPs, local oscillator leakage problems are avoided.
摘要翻译：电路接收第一信号（例如，基带信号）并将其与本地振荡器（LO）信号混合，并输出第二信号（例如，RFOUT信号）。该电路包括多个相同的混频器和分频器对（MFDP）电路。每个MFDP可以单独启用。每个MFDP包括混频器和分频器，为混频器提供本地版本的LO信号。 MFDP输出耦合在一起，使得第二信号（RFOUT）的输出功率是各种MFDP的组合输出功率。通过控制使能的MFDP的数量，控制第二信号的输出功率。由于MFDP都具有相同的布局，因此输出功率步长的精度提高。由于电路内的LO信号功率与启用MFDP的数量成比例地自动变化，因此避免了本地振荡器泄漏问题。

摘要： A digital-to-analog converter, RF transmit channel and method, for converting a digital signal of N bits having a set M of most significant bits and a set L of least significant bits to an analog signal, are disclosed. The digital signal defines a set of coded values which are converted to analog values and modulated on to a RF signal. The digital-to-analog converter includes a plurality of switches and an output stage, for providing at least a first differential output signal and a second differential output signal. The output stage modifies currents received from the plurality of switches, such that the value of the average output current of the first and second differential outputs signals is steered to a relatively low current value at the mid-point of the coded values.
