Synchronous DS-CDMA/FDMA PHY Proposal for IEEE 802.16.3

This document outlines a PHY proposal for IEEE 802.16.3 using a combined synchronous DSCDMA (S-CDMA) and FDMA scheme. The proposed PHY features adaptive QAM modulation, high-rate trellis and/or turbo coding, linear equalization along with power and timing control. Purpose To provide a description of a proposed physical layer specification for consideration by the IEEE 802.16.3 Task Group. Notice This document has been prepared to assist IEEE 802.16. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein.
