    • The performance of a RAKE receiver for indoor multipath WLAN applications on direct sequence spread spectrum signals having relatively short codeword lengths comprises a channel-matched filter and codeword correlator front end, plus a signal combiner to which the codeword correlation component is applied. The signal combiner is supplied with a bias-corrected input calculated by a distorted codeword signature (power) generator, which is operative to generate and store a set of N codeword power correction values. The signal combiner combines correction values into the codeword correlation for each potentially transmitted codeword S k . This serves to correct each correlation codeword metric by a de-biasing power component |S k | 2 for the unequal multipath-based distortions of the codeword energies. The output of the signal combiner is coupled to a peak detector, which selects a minimum distance-based 'de-biased' output as the transmitted codeword.
    • 用于室内多径WLAN应用的RAKE接收机对具有相对短的码字长度的直接序列扩频信号的性能包括信道匹配滤波器和码字相关器前端,以及加上码字相关分量的信号组合器。 信号组合器被提供有由失真的码字签名(功率)生成器计算的偏差校正的输入,其可操作以生成并存储一组N个码字功率校正值。 信号组合器将校正值组合为每个可能发送的码字Sk的码字相关。 这用于通过针对码字能量的不相等的基于多径的失真的去偏置功率分量| Sk | 2来校正每个相关码字度量。 信号组合器的输出耦合到峰值检测器,该峰值检测器选择最小的基于距离的“去偏置”输出作为发送的码字。

    • An improved trench MOS-gated device (200) comprises a monocrystalline semiconductor substrate (201) on which is disposed a doped upper layer (202). The upper layer includes at an upper surface (214) a plurality of heavily doped body regions having a first polarity and overlying a drain region (203). The upper layer further includes at its upper surface a plurality of heavily doped source regions (206) having a second polarity opposite that of the body regions. A gate trench (207) extends from the upper surface of the upper layer to the drain region (203) and separates one source region from another. The trench (207) has a floor (209) and sidewalls (208) comprising a layer of dielectric material and contains a conductive gate material (210) filled to a selected level and an isolation layer of dielectric material (212) that overlies the gate material and substantially fills the trench. The upper surface (213) of the overlying layer of dielectric material in the trench is thus substantially coplanar with the upper surface (214) of the upper layer (202). A process for forming an improved MOS-gate device provides a device whose gate trench is filled to a selected level with a conductive gate material, over which is formed an isolation dielectric layer whose upper surface is substantially coplanar with the upper surface of the upper layer of the device.
