Cooperative Communication and Shared Handoff among Base, Relay, and Mobile Stations in OFDMA Cellular Networks |
摘要 |
In a cellular network, symbols are encoded and modulated to produce a modulated signal The modulated signal is mapped to a subcarrier using a spatial mapping matrix. An inverse fast Fourier transform is applied to the mapped signal to produce groups of tones. The groups of tones are transmitting concurrently to multiple receivers using the same channel as orthogonal frequency-division multiplexing access (OFDMA) signals. There is one group of tones for each receiver.
