SUMMARY
The main technical objectives of the COPWIN (Coordinated MultiPoint Strategies for Future Wireless Networks) project are to design, implement and validate techniques exploring BSS (baseline system specification) collaboration for future wireless systems. The aim is to design and demonstrate practical multicell transmission and reception techniques that improve user’s fairness and throughput.

SOLUTIONS
- Designing practical precoders for the downlink of multicell MIMO-OFDM based networks
- Developing efficient multiuser detection techniques for the uplink of multicell MIMO SC-FDMA based networks.
- Designing efficient signalling strategies both for the feedback of wireless link information and distribution among the cooperating network elements, aiming to optimize the trade-off between achieved performance and signalling overhead, with particular emphasis will be placed on inter-cluster feedback and quantization strategies.
- Designing and optimising medium access control protocols for the considered clustered multicell architecture with joint scheduling and dynamic link adaptation.
- Assessing and validating the proposed downlink and uplink algorithms under realist scenarios, trough a system level simulator based on LTE specification.
- Developing an FPGA based testbed to demonstrate the feasibility of the proposed algorithms, integrating and characterising the promising algorithms
