摘要： A method for field error checking begins by decoding a predetermined pattern of a field of a frame to produce a decoded pattern. The method continues by determining, for the decoded pattern, a path metric distance of a predetermined state of a plurality of states of the decoding. The method continues by comparing the path metric distance with an excepted path metric distance for the predetermined state. The method continues by indicating a field error when the path metric distance compares unfavorably with the excepted path metric distance.
摘要翻译：用于场错误检查的方法通过对帧的场的预定模式进行解码来产生解码图案。该方法通过针对解码图案确定解码的多个状态的预定状态的路径度量距离来继续。该方法通过将路径度量距离与预定状态的例外路径度量距离进行比较来继续。当路径度量距离与例外路径度量距离不利地比较时，该方法继续指示场错误。

摘要： A pixel interpolation process is based on detection of a potential edge in proximity to a pixel being estimated, and the angle thereof. The potential edge and its angle is determined based on filtering of offset or overlapping sets of lines from a pixel window centered around the pixel being estimated and then cross-correlating the filter results. The highest value in the correlation result values represents a potential edge in proximity to the pixel being estimated and the index of the highest value represents the angle of the potential edge. This information is used in conjunction with other information from the cross-correlation and analysis of the differences between pixels in proximity to verify the validity of the potential edge. If determined to be valid, a diagonal interpolation based on the edge and its angle is used to estimate the pixel value of the pixel. Otherwise, an alternate interpolation process, such as vertical interpolation, is used to estimate the pixel value for the pixel.
摘要翻译：像素内插处理基于对被估计的像素附近的电位边缘的检测及其角度。基于以估计像素为中心的像素窗口的偏移或重叠线组的滤波确定潜在边缘及其角度，然后将滤波器结果互相关。相关结果值中的最高值表示接近被估计像素的电势边缘，最高值的索引表示电位边缘的角度。该信息与来自相邻像素之间的差异的互相关和其他信息结合使用以验证潜在边缘的有效性。如果确定为有效，则使用基于边缘及其角度的对角插值来估计像素的像素值。否则，使用诸如垂直内插的替代插值处理来估计像素的像素值。

摘要： A method for receiving high data rate wireless communication transmissions begins by receiving a plurality of radio frequency (RF) signals in accordance with a wireless communication standardized data rate on a plurality of RF channels. The method continues by converting each of the plurality of RF signals into a plurality of signals. The method continues by processing the plurality of signals at baseband or near baseband into media access control (MAC) data, wherein a number of the plurality of signals corresponds to an integer multiple. The method continues by processing the MAC data at a combination of wireless communication standardized data rates to produce recovered data.
