| 摘 要： | 揭示出采样定理存在的局限性，推导出了一个解决这一局限性的普适化采样定理公式。并由此证明，在存在码间相互干扰的情况下，在一定条件下，仍然可以无失真地恢复出样点值，而且Ｎｙｑｕｉｓｔ传输率可以超过。

| Abstract: | It is discussed in this paper that sampling theorem formula exists a confinement in engineering practice. Then a generalized sampling theorem formula is derived that can eliminate the confinement. Finally,it is proved by means of the generalized sampling theorem formula that under certain condition the sample values may be reproduced without distortion when the interference exists between the samples,and Nyquist transmission rate may be exceeded. |
