In conventional indoor optical wireless communication, the transmitter is usually empirically viewed as a source with a Lambertian radiation pattern. This paper comprehensively studies the impact of practical source radiation patterns on channel characteristics, including light-emitting diodes (LEDs) from Nichia and Lumileds Philips. Compared with the Lambertian pattern, differences in impulse and...
A new MIMO channel model based on angular-domain, double-directional channel model is proposed. Angular domain is a more appropriate coordinate to describe the MIMO channel, since the incoming rays and outgoing rays appear in clusters in the real world. This model is developed based on linear space and sampling theory and is applicable to any practical antenna geometry and includes the actual radiation...
