HYBRID ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACCESS SYSTEM AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide an OFDMA system including a transmitter 100 and a receiver 200.

SOLUTION: The transmitter 100 includes a first spread OFDMA subassembly 130, a first non-spread OFDMA subassembly 140 and a first common subassembly 150. The first spread OFDMA subassembly 130 spreads input data 101 and maps the spread data 103 into a sub-carrier 105 of a first group. The first non-spread OFDMA subassembly 140 maps input data 111 into a sub-carrier 115 of a second group. A first common subassembly 150 transmits the input data mapped into the sub-carriers of the first and second groups by using OFDMA.
