DH-PIM Employing LMSE Equalisation for Indoor Infrared Diffuse Links
نویسنده
چکیده
The performance of dual heard pulse interval modulation (DH-PIM) employing least mean square error equaliser (LMSE) in diffuse infrared indoor environment is presented. The work is based on the ceiling bounce channel model and the Monte Carlos simulation. A 3-tap LMSE equaliser is used and results are compared with unequalised DH-PIM and with DHPIM employing linear zero forcing equaliser (L-ZFE). The error performance and power penalties are compared with on-off keying (OOK), pulse position modulation (PPM) and digital pulse interval modulation (DPIM) techniques. The results show that DH-PIM with short pulse duration gives the best error performance and the most power penalty in highly dispersive environment.
