Hybrid orthogonal frequency division multiple access WTRU and method


Abstract
A hybrid orthogonal frequency division multiple access (OFDMA) wireless transmit/receive unit (WTRU) and method. A WTRU includes a transmitter and a receiver. The receiver processes received data to recover data mapped to the subcarriers using OFDMA. The receiver recovers first input data by separating user data from multi-user spread data and recovers second input data from non-spread data.
