Aiming at implementing the digital pulse interval modulation(DPIM) for optical wireless communications(OWC),a dual-mapping technique is presented.The scheme of DPIM train based upon the dual-mapping technique is given.Its slot error rate is derived for the avalanche photonic diode(APD) receiver model,and is compared with that of classical DPIM.Simulation results show that the dual-mapping DPIM(D-DPIM),which has a fixed slot length,only has marginally inferior error performance,but can solve waiting slots or buffer overflowing in comparison with DPIM.Hence,it is suitable for the optical wireless communication systems.
