Abstract: A sigma-delta modulator for an ADC, passes an input signal to a loop filter, then to a multi-bit quantizer of the modulator. An output of the quantizer is passed to a digital filter, and a feedback signal is passed back to the loop filter, the feedback signal having fewer bits than are produced by the multi-bit quantizer. The digital filter has an order greater than one in the passband of the sigma-delta modulator.

Abstract: In a communication device having a modem subsystem and an Application Processing Engine (APE) that share an IP address, port number conflicts are avoided by a Port Reservation Agent (PRA) running on the APE. Apps executing on the modem subsystem must request to register a port number with the PRA prior to using it. If the address is available, the PRA creates a port reservation socket and associates the port number with the requesting app. If the requested port number is not available, the PRA returns an error and the app must request a different address. To apps executing on the APE, the port reservation sockets appear as port numbers associated with other apps executing on the APE. In this manner, port number conflicts between the modem subsystem and the APE are avoided.

Abstract translation: 在具有共享IP地址的调制解调器子系统和应用处理引擎（APE）的通信设备中，通过在APE上运行的端口预留代理（PRA）来避免端口号冲突。 在调制解调器子系统上执行的应用程序必须在PRA使用之前请求注册一个端口号。 如果地址可用，则PRA创建一个端口预留套接字，并将端口号与请求应用相关联。 如果请求的端口号不可用，则PRA返回错误，并且应用程序必须请求不同的地址。 对于在APE上执行的应用程序，端口预留套接字显示为与在APE上执行的其他应用程序相关联的端口号。 这样就避免了调制解调器子系统与APE之间的端口号冲突。

Abstract: A process selects a Precoding Matrix Index (PMI) in a Multiple In Multiple Out (MIMO) receiver used in a wireless communications system including a base station communicating with User Equipments (UE) through a downlink and uplink channel. The base station applies a precoding on the transmit symbol vector based on a matrix selected from a set of predefined matrices and identified by a PMI index computed by the UE and forwarded to the base station via the uplink. The process includes estimating the MIMO channel matrix H of a given set of resources blocks comprising received symbol vectors, estimating the variance σ2 of the additive noise (AWGN), and computing for each particular matrix comprised within the set of predefined matrices a cost function representative of the orthogonality of the matrix MIMO channel matrix H. The process further includes comparing the values of the cost function and transmitting to the base station the index corresponding to the matrix corresponding to the best conditioned MIMO channel matrix according to the comparison of the values.

Abstract: A control circuit (115), a control method, a DC-DC converter and an electronic device are provided. The control circuit (115) is used to control the DC-DC converter to switch its operation modes. In the control circuit (115), whether mode of the DC-DC converter is to be switched is judged according to parameters of a first duration of an active duration and a second duration of an inactive duration. Comparison of analogue values is prevented, and as a result, the use of the analogue comparator is reduced, thus the influence of the semiconductor processes on designing a controller can be reduced.

Abstract: A composite electronic circuit assembly comprises two MOS or CMOS circuit dice (100, 200) superimposed inside a package. Different modules of the circuit assembly are distributed between the two dice based on the digital, analog, or hybrid nature of said modules. Such a distribution makes it possible to group together the digital modules of the circuit assembly in one of the die and the analog or hybrid modules in the other die. The production cost, development time, and electrical energy consumption of the circuit assembly may thus be reduced.

Abstract: A scheme determines the first significant path (FSP) of a received multipath signal, from data defining the relative delay and the amplitude of the individual signal paths occurring in a series of time frames. The scheme includes filtering the data to spread the signal paths, performing a persistence test between frames to reject spurious signal paths, combining the energy of the signal paths in a frame, applying a test to determine the time at which the combined energy satisfies a criterion, and selecting the FSP dependent on that time. The combined energy may be evaluated within a sliding window, and the position of the window within the frame determined that maximizes the combined energy. Alternatively, the combined energy may be evaluated as the cumulative energy through the frame, and the position determined at which the cumulative energy reaches a threshold.
