Fh Communication

Aiming at the problem of poor performance of suppressing the wide band jamming and fast following jamming in Frequency-Hopping (FH) communication system, a communication scheme by combination of the complementally transformed minimum variance with FH technique for arbitrary array (CTMV-FH) is proposed, based on the purpose to maximize the output Signal to Interference and Noise Ratio (SINR). Basic theory of CTMV is introduced. The algorithm is used to suppress the wide band jamming and fast following jamming. Simulation results show that the scheme can suppress the wide band jamming and fast following jamming effectively in FH communication system.

Feature Match

The purpose of this article is to outline a decision-making process and highlight which portions of the augmentative and alternative communication (AAC) evaluation process deserve special attention when deciding which features are required for a communication system in order to provide optimal benefit for the user. The clinician then will be able to use a feature-match approach as part of the decision-making process to determine whether mobile technology or a dedicated device is the best choice for communication. The term mobile technology will be used to describe off-the-shelf, commercially available, tablet-style devices like an iPhone®, iPod Touch®, iPad®, and Android® or Windows® tablet.

Children With Hearing Loss

The critical need to identify children with hearing loss and provide treatment at the earliest possible age has become increasingly apparent in recent years (Northern & Downs, 1978). Reduction of the auditory signal during the critical language-learning period can severely limit the child's potential for developing a complete, effective communication system. Identification and treatment of children having handicapping conditions at an early age has gained impetus through the Handicapped Children's Early Education Program (HCEEP) projects funded by the Bureau of Education for the Handicapped (BEH).
