The wireless extension of the JPEG 2000 standard formally known as JPWL is the newest international standard for still image compression. Different from all previous standards, this new standard was created specifically for wireless imaging applications. This paper examines the error resilience performance of the JPEG, JPEG 2000 and JPWL standards in combating multi-path and fading impairments in...
Recently, cooperative sensing which can enhance the sensing performance becomes popular in the design of cognitive radio (CR) networks. CR networks need reliable information exchange to conduct cooperative sensing, but it is difficult to transmit information for CR networks without licensed band over the air interface. In this paper, we propose to use spread spectrum technology to transmit low rate...
In OFDMA cellular system, the inter-cell interference is main interference of the system, which greatly degrades the system performance. In the inter-cell interference mitigation scheme, interference cancellation based on IDMA is a potential technology, especially in full-loaded scenario. Although it can enhance the system performance, its well work needs many information such as MCS, which makes...
