Bpsk Modulation

This paper mainly introduces the basic principles of BCH code, which is a type of error control codes. The error control system is an important method to improve the communication transmission system. Communication system that containing BPSK modulation is built by MATLAB and through simulating and analyzing the performance of BCH communication systems, it was discovered that the BCH code transmission characteristic has significant gain. This paper provides the theory basis for the projects that contain BCH code.

Abstract Although students may not become augmentative and alternative communication (AAC) clinical specialists, they often will work with individuals demonstrating complex communication needs who benefit from AAC. This necessitates knowledge of some basic principles of assessment including AAC assessment as a team process involving planning and implementing interventions for current and future communication needs; the inclusion of no-tech, low-tech, and high-tech communication systems; and assessing communication needs with partners in the individual's social network. The assessment also must include a capability profile and feature matching to select the appropriate components of the AAC system. Because the system we provide for today will become the system we use tomorrow, assessment must be considered an ongoing process throughout the lifespan of the individual.
