Multi-tone transceiver system using two steps of DMT-CMFB |
摘要 |
A wideband multi-tone transceiver system interoperable with Asymmetric Digital Subscriber Line (ADSL) transceiver system, and including a two-step transceiver system having a discrete multi-tone transceiver system and a cosine modulated filter bank (CMFB) transmultiplexer. The two-step transceiver system provides a physically transparent transmission channel to each sub-band signal by minimizing the interference between sub-bands regardless of the transmission channel characteristics. The two-step transceiver system is realized with a comparably simple structure, and the circuit size is drastically reduced by sharing the FFT function with other sub-channels with the maximal utilization of the high-speed circuit when realizing each sub-channel's DMT modulation and demodulation function. |
