Fecha de publicación: | 1999 | Publicación seriada: | Proceedings of SPIE - The International Society for Optical Engineering | Resumen: | A low complexity system of optical links using indoor unguided infrared channels and direct-sequence code division multiple access is presented. Direct sequence spread spectrum techniques improve performance of optical unguided links with background illumination noise, and multipath propagation. It also allows several users to use code division multiple access, to share the same infrared channel. In the system designed, optical infrared carrier is intensity modulation by a direct-sequence spread spectrum electrical signal, driving the optical emitter. Infrared radiation is directly detected by receiver photodiode. | URI: | http://hdl.handle.net/10553/50083 | ISSN: | 0277-786X | Fuente: | Proceedings of SPIE - The International Society for Optical Engineering[ISSN 0277-786X],v. 3850, p. 92-99 |
