    • Dynamic spectral assignment in an ad hoc network of wireless network nodes (200) includes determining (306) a set of allowed frequencies that can be used by the ad hoc network and a corresponding index value for each of the allowed frequencies. An allowed list is created (308) and comprised of the index values (312) arranged in a deterministic order. A pointer (604) into the allowed list (600) is determined for each one of a total of Nhop frequency hops of a hopping sequence. Each pointer specifies one of the allowed frequencies (601) to be used for a corresponding one of the frequency hops. A wireless frequency hopping communication session is performed among a plurality of the nodes in the ad hoc network, using a frequency for each hop of the hopping sequence as specified by the pointers (604).

    • A communication system from maintaining synchronization includes a communication signal comprising a carrier and a data signal that is sent from a transmitter to a receiver which includes a phase lock loop. The receiver compares the output of a Viterbi decoder with the output of a quick decision circuit. The Viterbi decoder, which incorporates traceback, determines the minimum aggregate Euclidean distance for multiple symbols. The quick decision circuit determines the minimum Euclidean distance for a single symbol without decoding the symbol. A delay circuit is placed in series with the quick decision circuit to compensate for the traceback delay in the Viterbi decoder. If the difference in the output signals of Viterbi decoder and the quick decision circuit is greater than a predetermined threshold, the phase error signal in the phase lock loop is prevented from updating the phase lock loop filter. A synchronization loss detector may also be used to prevent the phase error signal from updating the phase lock loop filter if synchronization loss is detected.
    • 保持同步的通信系统包括通信信号,该通信信号包括载波和从发射机发送到包括锁相环的接收机的数据信号。 接收机将维特比解码器的输出与快速判定电路的输出进行比较。 包含追溯的维特比解码器确定多个符号的最小聚合欧几里德距离。 快速判决电路确定单个符号的最小欧几里德距离,而不对码元进行解码。 延迟电路与快速判定电路串联放置以补偿维特比解码器中的回溯延迟。 如果维特比解码器和快速判定电路的输出信号的差大于预定的阈值,则防止锁相环中的相位误差信号更新锁相环滤波器。 如果检测到同步丢失,则同步丢失检测器也可用于防止相位误差信号更新锁相环滤波器。
