Quantization is an important operation in digital communications systems. Quantizer not only introduces quantization noise but it also changes the statistical properties of the quantized signal. Furthermore, quantization noise cannot be always considered as an additive source of Gaussian noise. It depends on the input signal probability density function. In an orthogonal-frequency-division- multiplexing...
The problem of constructing lattices such that their quantization noise approaches a desired distribution is studied. It is shown that asymptotically is the dimension, lattice quantization noise can approach a broad family of distribution functions with independent and identically distributed components.
