HYBRID ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACCESS SYSTEM AND METHOD

摘要

PURPOSE: A hybrid orthogonal frequency division multiple access system is provided to accomplish the frequency reuse factor as 1 by performing a control to releasing interference between cells. CONSTITUTION: A hybrid OFDMA system comprises a transmitter(100) and a receiver(200). The transmitter comprises a diffusion OFDMA sub assembly(130), a despreading OFDMA sub assembly(140), and a common sub assembly(150). The diffusion OFDMA assembly comprises a diffusion unit(102) and a first subcarrier mapping unit(104). The despreading OFDMA sub assembly comprises the serial-parallel converter(112) and a second subcarrier mapping unit(114).
