Carrier-phase synchronization can be approached in a general manner by estimating the multiplicative distortion (MD) to which a baseband received signal in an RF or coherent optical transmission system is subjected. This paper presents a unified modeling and estimation of the MD in finite-alphabet digital CoMMUnication systems. A simple form of MD is the camer phase exp GO) which has to be estimated and compensated for in a coherent receiver. A more general case with fading must, however, allow for amplitude as well as phase variations of the MD. We assume a state-variable model for the MD and generally obtain a nonlinear estimation problem with additional randomly-varying system parameters such as received signal power, frequency offset, and Doppler spread. An extended Kalman filter is then applied as a near-optimal solution to the adaptive MD and channel parameter estimation problem. Examples are given to show the use and some advantages of this scheme.

Abstract—Mobile devices performing video coding and streaming over wireless and pervasive CoMMUnication networks are limited in energy supply. To prolong the operational lifetime of these devices, an embedded video encoding system should be able to adjust its computational complexity and energy consumption as demanded by the situation and its environment.

MIDlet通過藍(lán)牙與電腦通信的案例,This resource demonstrates how to create Java™ applications that use Bluetooth CoMMUnication between a PC and a mobile device. The document focuses, from Java programming point of view, on how to configure and use two alternative PC-side solutions: COM-based and JSR-82-based solutions. The package includes several code examples both for PC and mobile devices.

老外自編串口組件及串口程序: Commu, a testform to check if everything is working correctly. XON/XOFF check is not yet implemented. So good luck with CoMMUnication.

CANopen is a networking system based on the CAN serial bus. CANopen assumes that the device’s hardware has a CAN transceiver and CAN controller as specified in ISO 11898. CANopen profile family specifies standardized CoMMUnication mechanisms and device functionality. The profile family is available and maintained by CAN in Automation (CiA), the international users’ and manufacturers’ group and may be implemented license-free.

SDP, Service Delivery Platform, is more for telecom operators who want to manage the Data Service better delivered to the end device users by bridging with back-end content providers. Operators rely on the content provider to create & distribute data content to different types of devices. This is different from the open world in the internet CoMMUnication. Operators must control who can access what content based on his rate plans. Also, based the content access results, the process will be recorded as the transaction records based on which billing statements can be generated to collected the money and shared by operators and content providers. I am working on the conceptual architecture level and the real implementation is very complicated due to too many types of service from different content providers to different types of devices based on the different types of the rate plans.
