摘要： Spherical microphone arrays capture a three-dimensional sound field (P(Ωc, t)) for generating an Ambisonics representation (Anm(t)), where the pressure distribution on the surface of the sphere is sampled by the capsules of the array. The impact of the microphones on the captured sound field is removed using the inverse microphone transfer function. The equalisation of the transfer function of the microphone array is a big problem because the reciprocal of the transfer function causes high gains for small values in the transfer function and these small values are affected by transducer noise. The invention estimates the signal-to-noise ratio between the average sound field power and the noise power from the microphone array capsules, computes the average spatial signal power at the point of origin for a diffuse sound field, and designs in the frequency domain the frequency response of the equalisation filter from the square root of the fraction of a given reference power and the simulated power at the point of origin.
摘要翻译：球形麦克风阵列捕获三维声场（P（＆OHgr; c，t）），用于产生Ambisonics表示（Anm（t）），其中球体表面上的压力分布由阵列的胶囊。使用反向麦克风传递功能可以消除麦克风对拍摄声场的影响。麦克风阵列的传递函数的均衡是一个大问题，因为传递函数的倒数对传递函数中的小值造成高增益，这些小值受传感器噪声的影响。本发明估计了来自麦克风阵列胶囊的平均声场功率和噪声功率之间的信噪比，计算扩散声场的原点处的平均空间信号功率，并且在频域中设计来自给定参考功率的分数的平方根的均衡滤波器的频率响应和原点处的模拟功率。

摘要： A fast retransmission method by introducing the internal node under better channel condition to join the work of retransmission after the destination node sends out the packet loss indication for unicast services. Extended to serve multicast services, a system comprising a plurality of nodes utilizes the farthest node in each branch from the source to transmit an acknowledge signal when packet loss occurs. The system then enables the closest node to the acknowledging node to retransmit the requested packet, thereby improving the target packet hit rate and data integrity with less retransmission steps.

摘要： A system and method for interfacing multiple SoCs (System on a Chip) to a single, shared memory device are provided. The system and method of the present disclosure provides for controlling the downloading of operating code to two or more SoC controller circuits sharing a memory containing the operating code and a common communications bus, where each controller is a master controller of the communications bus in normal operation. The system and method involves sequentially controlling access of each of the controller circuits to the communications bus to allow each device to separately download the common operating code. The system and method utilize a separate initializing circuit or device along with chaining the controllers together in a series such that each controller be held in a reset state to prevent communications bus access until the previous controller in the chain has completed its code download.
