Adaptive Subcarrier Assignment and Power Distribution in Multiuser OFDM Systems with Proportional Data Rate Requirement

A low complexity dynamic subcarrier and power allocation methodology for downlink communication in an OFDM-based multiuser environment is developed. The problem of maximizing overall capacity with constraints on total power consumption, bit error rate and data rate proportionality among users requiring different QOS specifications is formulated. Assuming perfect knowledge of the instantaneo...

Subcarrier Multiplexing in Optical Networks

This paper describes the applicability of subcarrier multiplexing to light wave multiple-access networks. It is shown how currently available microwave and light wave components can be used, by using subcarrier multiplexing, to provide high-capacity networks and also how can increase the number of users who support the network.

Stable-matching-based subcarrier assignment method for multimode PON using a multicarrier variant of subcarrier multiplexing

In this paper, an adaptive subcarrier assignment method based on a stable matching algorithm is considered. From the performance comparison with other assignment methods (Hungarian-algorithm-based, contiguous and interleaved), our assignment method, while of relatively low complexity, resulted in a satisfactory performance in terms of per-ONU and overall achievable throughputs, and also it resp...

Superposition Coding Scheme for Subcarrier & Bit Allocation in OFDM System

Orthogonal Frequency Division Multiple Access (OFDMA) refers to aradio transmission technique based on dividing the frequency channelinto narrowband sub-channels. In this dissertation studied that margin adaptive superposition coding (MA-SC) algorithm and rate adaptive superposition coding (RA-SC) algorithm, where at most two users can share each subcarrier as compared to MA and RA algorithm, w...

Subcarrier Multiplexing for High-Speed Optical Transmission

The performance of high-speed digital fiber-optic transmission using subcarrier multiplexing (SCM) is investigated both analytically and numerically. In order to reduce the impact of fiber chromatic dispersion and increase bandwidth efficiency, optical single-sideband (OSSB) modulation was used. Because frequency spacing between adjacent subcarriers can be much narrower than in a conventional D...
