By using the residual source redundancy to achieve the shaping gain. a joint source-channel coded modulation (JSCCM) system has been proposed as a new solution for probabilistic amplitude shaping (PAS). However. the source and channel codes in the JSCCM system should be designed specifically for a given source probability to ensure optimal PAS performance. https://parisnaturalfoodes.shop/product-category/sleep-relax-extract/
