Special attention was paid to improving channel robustness 人們對改進(jìn)信道的健壯性特別關(guān)注。
Improved channel access during cfp , and the ability to retain polling for backward compatibility , result in more efficient polling 在cfp中改進(jìn)的信道訪問和維持輪詢向后兼容性的能力,帶來了更高效率的輪詢。
An improved channel estimation scheme are offered , which resists noise efficiently and provides accurate channel estimation coefficient 原有信道估計方案對噪聲敏感,當(dāng)存在噪聲時,信道估計性能嚴(yán)重惡化。
Based on the idea of contention reservation access and polling transmission , user - dependent perfect - scheduling multiple access ( upma ) protocol is presented , which supports both node mobility and multi - hop network architecture . it improves channel utilization greatly and guarantees that a node accesses the channel rapidly 基于有效競爭預(yù)約接入、無沖突輪詢傳輸?shù)乃枷胩岢隽嗽跓o線adhoc網(wǎng)絡(luò)中支持節(jié)點移動性和多跳網(wǎng)絡(luò)結(jié)構(gòu)的依據(jù)用戶妥善安排的多址接入( upma )協(xié)議。
