Nolan, K.E, Mackenzie, P., and Doyle, L.E ‘OFDM sub-carrier allocation algorithm for a multiple user data enhanced radio server (MUDERS) using a general purpose processor platform’ in Proceedings of 4th Software Defined Radio (SDR) Forum Technical Conference, Phoenix, Arizona, Nov 15-18th, 2004, pp 1-6
This paper presents a novel spectrum-allocation technique
designed for a high data-rate and spectrally-efficient
multiple-user wireless system. The core of this system is a
reconfigurable radio, implemented on a General-Purpose
Processor (GPP) platform. A type of Dynamic Orthogonal
Frequency Division Multiplexing Multiple Access
(DOFDMA) is used to transmit a multiplex of several
information sources. A novel means of sub-carrier
allocation is utilised allowing the spectrum allocation for
each service to be varied according to the spectrum-usage
at the time of the request and priority of the particular
service. In addition a novel technique that enables frame
synchronisation, carrier-frequency offset estimation and a
means of notifying the remote receiver(s) of the subcarrier
allocation using a single OFDM symbol will be
presented. A prototype model for the Multiple User Data
Enhanced Radio Server (MUDERS) modulator will be
presented, focusing on a means of conveying the spectrum
allocation information to a remote receiver(s).
