EXIT chart aided design of near-capacity UWB impulse radio using self-concatenated codes

A near-capacity Time Hopping (TH) Pulse Position Modulation (PPM) based Ultra Wide Band (UWB) Impulse Radio (IR) system is proposed, which invokes iteratively detected Self-Concatenated Convolutional Codes (SeCCC) employing Extrinsic Information Transfer (EXIT) charts. The TH-PPM-UWB-IR-SeCCC system configuration is capable of operating within about 0.9dB of the information-theoretic limits.
