    • An adaptive edge-preserving smoothing filter effectively reduces noise levels while preserving fine structures in data. The behavior of the filter is controlled easily by two control parameters. To adaptively control the behavior of the filter, the control parameter, .alpha., can be set as a function of the local directional variances. The control parameter, .beta., can be set as a function of all of the directional variances and directional means. The filter includes; a compute means which receives the filter window size, the number of filter directions and input data, adaptive weighting parameter map means which receives the control parameter, .alpha., adaptive weighting process means, adaptive combination parameter map means which receives the control parameter, .beta., and final compute means which provides the filtered output data.
    • 自适应边缘保持平滑滤波器有效地降低噪声水平,同时保留数据中的精细结构。 过滤器的行为由两个控制参数容易控制。 为了自适应地控制过滤器的行为,可以将控制参数α设置为局部方向方差的函数。 控制参数β可以设置为所有方向方向和方向方式的函数。 过滤器包括 接收滤波器窗口尺寸,滤波器方向数量和输入数据的计算装置,接收控制参数的自适应加权参数映射装置,α,自适应加权处理装置,接收控制参数β的自适应组合参数映射装置, 以及提供经滤波的输出数据的最终计算装置。

    • A method for Hybrid Automatic Repeat Request (HARQ) combination is disclosed. The method includes that: externally configured parameters relevant to HARQ combination are received, and an identifier ddr2switch of DDR2 switching is calculated to acquire addresses involved before and after the HARQ combination; it is determined, according to the parameters and the addresses involved before and after the HARQ combination, whether the HARQ combination is needed to be performed; and when it is determined that the HARQ combination is needed to be performed, data in a DDR2 are read and stored into a first data cache random access memory RAMA; and a HARQ combination calculation is performed, and the calculation result is stored into a second data cache random access memory RAMB. A device for HARQ combination is further disclosed. The technical solutions provided in the disclosure are based on a latest interference cancellation algorithm, greatly increase the success probability of decoding, saves the storage space of a DDR2 and improves the reading or writing efficiency.
