并发码：一种对噪声和丢失鲁棒的全息型编码
Concurrent codes: A holographic-type encoding robust against noise and loss
摘要：
并发编码是一种具有“全息”类型属性的编码方案，这里示出了该编码方案对于大量的噪声和信号损失是鲁棒的。这种单一编码方案能够同时纠正随机错误和突发错误，但不依赖于循环码。一个简单实用的方案已被测试，显示完美的解码时，信噪比为18dB的顺序。当丢失40%的传输的连续块时，相同的方案也显示完美的重建。此外，该方案在发射功率要求方面比等效循环码效率高50%。一个简单的模型，描述了解码的过程中，可以确定的计算负荷，将预期的，以及描述的关键水平的噪声和丢失的数据开始产生错误的消息。
英文摘要：
Concurrent coding is an encoding scheme with "holographic" type properties that are shown here to be robust against a significant amount of noise and signal loss. This single encoding scheme is able to correct for random errors and burst errors simultaneously, but does not rely on cyclic codes. A simple and practical scheme has been tested that displays perfect decoding when the signal to noise ratio is of order -18dB. The same scheme also displays perfect reconstruction when a contiguous block of 40% of the transmission is missing. In addition this scheme is 50% more efficient in terms of transmitted power requirements than equivalent cyclic codes. A simple model is presented that describes the process of decoding and can determine the computational load that would be expected, as well as describing the critical levels of noise and missing data at which false messages begin to be generated.
