Abstract
The Wireless Gigabit/s Local-Area Network (WGLAN) project is aimed at providing highspeed data transmission between the Next Generation Internet and end-use devices within the home or office environment. The design of the digital signal processing (DSP) required at the physical layer of the network is the focus of this thesis. In particular, this thesis models the indoor radio channel environment at the 5.x GHz Unlicensed National Information Infrastructure (U-NII) frequency band, and proposes a multipath-resistant transceiver design based on Orthogonal Frequency Division Multiplexing (OFDM) with adaptive multilevel Quadrature Amplitude Modulation (M-QAM). The proposed network design allows two-way communication through a Time Division Duplexing (TDD) scheme and provides multiuser support through a series of algorithms that establish session links and allocate subchannels among devices in an optimal way. Finally, a custom-written software simulation is used to estimate the bit error rate (BER) network performance under different channel conditions.
