摘要：
To increase the throughput of transmission systems, MIMO transmission have become a natural path. Two different MIMO schemes can be envisioned: point to point communications and multi-point to point communications. We propose in this paper to study the performances of multi-point to point communication (also referred to as multi-user transmissions) for different receivers and with or without channel estimation. The proposed channel estimator is a multi-user maximum likelihood estimator achieving both synchronization and the channel estimates. This work is partially supported by the IST project STRIKE (FP5 IST-2001-38354).
