Highlights：

• For the Laplace distributed host signal, obtain the optimal decoder of the ASS scheme.

• Analyze the decoding error probability of the ASS scheme.

• Propose the new CASS scheme for the Laplace distributed host signal, and analyze its decoding error probability.

• Perform simulations to demonstrate the superiority of the proposed CASS scheme over the ASS scheme.

• As an extension, discuss the CASS scheme for the generalized Gaussian distribution (GGD) distributed host signal.
