| Abstract: | Based on the technology of pseudo-chaotic time hopping (PCTH) applying to ultra-wide bandwidth (UWB) communications, a new structure for the pseudo-chaotic encoder using double-tent mapping was presented, and a decoding scheme was given accordingly. The theoretical analysis and Matlab simulation result show that compared with tent-mapping, this scheme has a stronger anti deciphering capabilities and better security without lowering the quality of communication. |
