Thesis on mimo-ofdm performance analysis

The multi-stream transmission via Multiple-Output Multiple-Input MIMO systems achieves different gains using beamforming, spatial diversity and spatial multiplexing techniques. The multi-carrier modulation via Orthogonal Frequency Division Multiplexing OFDM enhances spectral efficiency and facilitates using simple transceiver structures for broadband communications. The derived techniques are needed in network planning and optimization in order to analyze coverage, interference, frequency utilization, traffic loading.

Efficient evaluation of a desired combination of these dimensions to support multiple technologies and standards presents a significant challenge. We study the feasibility of a multiprotocol architecture without sacrificing the Quality of Service. An architecture facilitating such a mechanism can be implemented at different layers in the network stack with each layer offering a tradeoff between complexity and latency.

Careful analysis of the physical layer reveals that most blocks of the transceiver can be reused for different protocols without significant architectural change.

In addition to the feasibility analysis, we also identify common blocks in the network stack that could be possibly reused buying us significant hardware gains without sacrificing the aggregate system throughput.

In this thesis, a MIMO-OFDM system that employs Walsh sequences as block coding is designed. Simulation studies show that the proposed system exhibits high performance and comparisons show that it has low complexity compared to some of the previous systems.

Our study presents the gate count complexity and the performance analysis of programmable radio architecture with the In this thesis, we demonstrate that multiple protocols can be supported using the same hardware under acceptable latency requirements.

Complexity of the system in terms of gate count has been determined. It has been found that for shorter frame sizes, it is better to process less number of OFDM symbols at a time.

However, for larger frame sizes, it is beneficial to process large number four to eight of OFDM symbols at a time. Also, the minimum clock rate required to run the hardware, would vary depending upon the number of OFDM Symbols processed.
