Abstract |
|
The number of personal computers and personal digital assistants for indoor use are rapidly growing in offices, manufacturing floors, shopping areas and warehouses. In near future, one will find very often several such devices clustered within small indoor areas. To meet these requirements optical wireless (IR) technology seems to be ideal for wireless communication systems of the future. It can provide cable free communication at very high bit rates (a few Gbps as compared to tens of Mbps supported by radio). In indoor optical wireless systems, laser diodes (LDs) or light emitting diodes (LEDs) are used as transmitter and photo-diodes as the receivers for optical signals. These LED are Lambertian source, therefore light is not uniformly distributed and thus power variation and in turn BER varies. In this paper it is shown that by adding SOAs in photo-detector can improve BER performance. |
