METHOD AND APPARATUS FOR CONSTANT ENVELOPE ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING IN A WIRELESS SYSTEM

摘要

In a wireless communication system comprising at least one wireless transmit/receive unit (WTRU), a base station, and a radio network controller (RNC), a method for constant envelope orthogonal frequency division multiplexin (CE-OFDM) modulation (430) comprises the WTRU (110) performing an inverse transform on the data (420). The WTRU next performs constant envelope (CE) modulation on the data and transmits the CE-OFDM data to the base station. The base station receives the data and CE demodulates the data. The base station performs a transform on the demodulated data.
