Loosely Synchronized (LS) codes can be used as spreading codes in quasi­ synchronous code-division multiple-access (QS-CDMA) systems. In such CDMA systems, close control of synchronization is achieved at the chip level, interme­ diate between that in synchronous CDMA and that in…

After establishing itself in the radio domain, Spread spectrum code-division multiplexing/multiple-access (CDMA) has seen a recent upsurge in optical domain as well. Due to its fairness, flexibility, service differentiation and increased inherent security, CDMA is proved to be m…

This thesis explores reinforcement learning (RL) based approaches to create adaptive Medium Access Control (MAC) protocols that learn from past transmission history. As apposed to canonical RL algorithms, a policy tree is used to represent both the decision space and the environ…
