| 英文摘要 | A highly efficient multi-access scheme of broadband power line (bpl) communication, named as ofdm-bps-opdma, is proposed based on the orthogonal pulse division multiplexing access (opdma), barker-code-based spectrum spreading (bss) and orthogonal frequency division multiplexing (ofdm) method. the orthogonal pulses are generated by using the eigenvectors of hermitian matrix. at the same time, a specific pulse will be allocated to every user of the communication system. the transmitting data are first modulated by ofdm. then, it is processed with opdma and bss. finally, the data is sent to the power line channel. on the receiving side, the data is processed with bss demodulation, opdma demodulation and ofdm demodulation, and the receiving data for each user is acquired. because of the orthogonality between these pulses, the multi-user interference could be eliminated; when bss is used, the waveform restoration is enhanced. meanwhile, with the help of ofdm, the multi-path interference is mitigated. particularly, all users can share the resources of time and spectrum without interfering with others, and get excellent reliability in the concerned scheme. when ofdm is used, the sub-carriers may be allocated dynamically, and the legal radio frequency band could be shunned by sharing the common bandwidth with other communication systems. copyright (c) 2009 john wiley & sons, ltd. |
