Pilot assignment schemes for Massive MIMO systems

– cooperated with Huawei Technologies Co. Ltd.                                           Oct. 2012 - Apr. 2013

 

  • Analysed the pilot assignment problem in multi-cell multi-user massive MIMO systems to alleviate the inter-cell interference  (pilot contamination).

  • Proposed three low-complexity pilot assignment algorithms, including the greedy algorithm, the tabu search algorithm and the greedy tabu search algorithm to enhance system sum rates with low complexity.

 

 

Spatial orthogonality-based pilot reuse for Massive MIMO transmission           Apr. 2013 - Jul. 2013

 

  • Formulated the close-form expression of the non-asymptotic DL achievable rate by exploiting the second-order channel statistical information.

  • Presented the spatial orthogonality condition for inter-cell pilot reuse without rate loss.

  • Proposed a spatial orthogonality-based greedy pilot assignment algorithm to improve system sum rate performance.

Antenna selection for Multi-user Massive MIMO system

– cooperated with Pro. Yindi Jing, Albert University                                       Jul. 2013 - Apri. 2014

 

  • Analysed the BS antenna selection and user scheduling problem for Multi-user Massive MIMO systems by exploiting instantaneous or statistical channel state information to reduce the hardware complexity and cost.

  • Designed four antenna selection and user scheduling algorithms, including the rate-based descending antenna selection, the rate based ascending antenna selection, joint transmit and receive antenna selection, and distributed transmit and receive antenna selection.
