Hybrid Multiple-Access Techniques for Communication Networks

本研究是针对混合随机存取系统的分析 其使用多用户编码和冲突的组合 分辨率算法，以适应突发传输 在一个单一的通信信道上的许多独立用户。 的 其主要思想是避免T个或更少同时用户之间的冲突 通过使用多用户码和解决偶然的冲突 通过使用冲突解决方案， 算法 因此，吞吐量和延迟性能的增益可以是 如果接近T个用户同时发送，则预期会出现这种情况，但是 如果只有一个用户传输，则必须支付罚款，因为 几乎所有多用户码对称码率必须小于 而不是一个用户。其中一个主要目标是 研究的目的是确定多用户代码 必须具有使得混合随机接入系统的使用 产生比未编码随机访问更好的整体性能 系统

This research is the analysis of hybrid random-access systems which use a combination of multi-user coding and collision resolution algorithms to accommodate the bursty transmissions of many independent users on a single communications channel. The main idea is to avoid collisions among T or less simultaneous users by the use of multi-user codes and to resolve occasional collisions among more than T users by the use of a collision resolution algorithm. A gain in throughput and delay performance can thus be expected if close to T users transmit at the same time, but a penalty must be paid if only one user transmits because the symmetric code rate of almost all multi-user codes must be less than one for each individual user. One of the major goals of this research is to determine the properties which a multi-user code must possess such that the use of a hybrid random access system yields better overall performance than an uncoded random access system.
