    • Methods and apparatus are provided for N+1 packet level mesh protection. An error correction encoding method is provided that assembles M-T data packets; appends a sequence number and a payload integrity check to each of the M-T data packets; and creates T protection packets having the sequence number and payload integrity check, wherein a payload for each of the T protection packets are formed from corresponding symbols in the M-T data packets. An error correction decoding method is also provided that receives a plurality of error-free packets and one or more packets having an error; and reconstructs the one or more packets having an error by applying block erasure decoding to said plurality of error-free packets, whereby one packet having an error can be reconstructed for each protection packet used to encode the received packets.
    • 提供N + 1数据包级网格保护的方法和装置。 提供组合M-T数据包的纠错编码方法; 对每个M-T数据包附加序列号和有效载荷完整性检查; 并创建具有序列号和有效载荷完整性检查的T保护分组,其中每个T保护分组的有效载荷由M-T数据分组中的对应符号形成。 还提供一种纠错解码方法,其接收多个无错误分组和一个或多个具有错误的分组; 并且通过对所述多个无错误分组应用块擦除解码来重建具有错误的一个或多个分组,由此可以针对用于对接收的分组进行编码的每个保护分组重构具有错误的一个分组。

    • A microwave frequency detection receiver for receiving an incoming analog radar signal, converting the radar signal into digital form, and performing a table lookup algorithm for detecting frequency and amplitude of the incoming signal with respect to time. The table lookup algorithm is in the form of a three point best-fit sinusoidal approximation of frequency and amplitude for processing successive digital input signal samples processed in groups of three. Digital sampling of the input signal coupled with the novel table lookup algorithm results in detection of frequency and amplitude characteristics on an intrapulse basis.
    • 一种微波频率检测接收机,用于接收输入的模拟雷达信号,将雷达信号转换为数字形式,并执行用于检测输入信号相对于时间的频率和幅度的表格查找算法。 表查找算法采用频率和幅度的三点最佳拟合正弦近似的形式,用于处理三组中连续的数字输入信号样本。 与新颖的表查找算法相结合的输入信号的数字采样导致在脉冲基础上检测频率和幅度特性。
