LiUMIMO: A MIMO Testbed for Broadband Software Defined Radio (Computer Project)

In order to keep up with the increasing demand on speed and reliability in modern wireless systems, new standards have to be introduced. By using Multiple Input Multiple Output technology (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) technologies the performance can be increased dramatically. Forthcoming standards such as WLAN 802.11n, WiMax and 3GPP LTE are all taking advantage of MIMO […]

Impact of Crosstalk on Indoor WDM Optical Wireless Communication Systems

In this paper, we investigate the impact of optical crosstalk on our recently proposed indoor gigabit optical wireless (OW) communication system incorporating wavelength division multiplexing (WDM). A theoretical model that allows this impact to be assessed has been proposed. The analytical results are validated via experiments. We show that the power penalty due to crosstalk in our proposed indoor WDM […]

Embedding Data in an Audio signal, using Acoustic OFDM (Electronics Project)

The OFDM technology has been extensively used in many radio communication technologies. For example, OFDM is the core technology applied in WiFi, WiMAX and LTE. Its main advantages include high bandwidth utilization, strong noise immunity and the capability to resist frequency selective fading. However, OFDM technology is not only applied in the field of radio communication, but has also been […]
