Research Areas

The focus of research at CEWiT is on broadband wireless technologies. In particular, current research is targeted towards the 3GPP Rel-9 (and higher) and on the IEEE 802.16m standards. As part of this, following are some of the research topics that are being investigated:

  1. High data-rate spatial multiplexing, space-time coding and space-frequency coding (SFC) schemes

  2. Interference mitigation schemes for downlink and uplink in broadband systems

  3. Reduction of PHY/MAC overheads to increase the throughput.

  4. Peak-to-average power ratio (PAPR) reduction for uplink.

  5. Flexible frequency reuse in wireless braodband systems

  6. Advanced MIMO schemes for throughput improvement.

Besides research into PHY and MAC layers, CEWiT is also investigating issues at the higher layers, including:

  1. End-to-end QoS in heterogeneous wireless networks

  2. Efficient encoding schemes for SMS for Indian Languages

To support the Layer-1 and Layer-2 research, CEWiT is also developing a broadband wireless simulator BWSim which includes modules for both 3GPP and IEEE 802.16 standards.
