Multiclass systems with different Quality of Service (QoS) requirements are essential in nowadays Ethernet passive optical networks (EPON). In this paper, we propose a code division multiple access (CDMA) enabled dynamic power and bandwidth allocation (DPBA) algorithm for multiclass system. The novelty of the proposed algorithm is the resource allocation components: power control (PC) and bandwidth...
In this paper, a code division multiple access (CDMA) enabled dynamic bandwidth allocation (CDBA) algorithm is proposed for the upstream access scheme for Ethernet passive optical networks (EPON). The CDBA algorithm is based on two major components: The first is the parallel transmission capacity offered by CDMA according to the quality of service (QoS) requirement and the second component is the...
In this paper, a code division multiple access (CDMA) enabled dynamic bandwidth allocation (CDBA) algorithm is proposed for the upstream access scheme for Ethernet passive optical networks. The CDBA algorithm is based on two major components. The first is the parallel transmission capacity offered by CDMA according to the quality-of-service requirement, and the second is the scheduling algorithm,...
Throughout this paper, a unified analytical framework is presented emphasizing the impact of optical hard limiter (OHL) on the bit-error-rate (BER) performance of the optical overlapped code division multiple access (OV-CDMA) system. Results show that the performance of OV-CDMA system may be highly improved when using OHL.
This paper addresses the problem of resource allocation for a multiclass time-slotted optical overlapped code-division multiple-access (OV-CDMA) network. A fair resource allocation (FRA) scheme is considered with the quality of service (QoS) requirements on both physical layer signal-to-interference ratio (SIR) and MAC layer average packet delay. A cross-layer approach in allocating the transmission...
