Pseudorandom encoding with quantized real modulation values encodes only continuous real-valued functions. However, an arbitrary complex value can be represented if the desired value is first mapped to the closest real value realized by use of pseudorandom encoding. Examples of encoding real- and complex-valued functions illustrate performance improvements over conventional minimum distance mapping methods in reducing peak sidelobes and in improving the uniformity of spot arrays.
具有量化实调制值的伪随机编码仅对连续实值函数进行编码。然而,如果首先将所需值映射到通过使用伪随机编码实现的最接近实值,则可以表示任意复数值。对实值和复值函数进行编码的示例说明了与传统最小距离映射方法相比,在降低峰值旁瓣和提高光斑阵列均匀性方面的性能提升。
