Information capacity and power control in single-cell multiuser communications
Raymond Knopp,Pierre A. Humblet +1 more
TL;DR: By examining the bit error-rate with antipodal signalling, it is shown that an increase in capacity over a perfectly-power controlled (Gaussian) channel can be achieved, especially if the number of users is large, and the inherent diversity in multiuser communications over fading channels is shown.
Journal ArticleDOI
On coding for block fading channels
Raymond Knopp,Pierre A. Humblet +1 more
TL;DR: It is shown that high diversity can be achieved using relatively simple codes as long as very high spectral efficiency is not required and in some cases, performances approaching the information-theoretic bounds.
Journal ArticleDOI
OpenAirInterface: A Flexible Platform for 5G Research
TL;DR: This work presents OpenAirInterface (OAI) as a suitably flexible platform for experimentation modes from real-world experimentation to controlled and scalable evaluations while at the same time retaining backward compatibility with current generation systems.
Proceedings ArticleDOI
A practical method for wireless channel reciprocity exploitation through relative calibration
TL;DR: Experimental results confirm the validity of the proposed linear reciprocity model, and of the calibration approach, which lets the transmitter acquire knowledge of the downlink channel state from the uplink channel estimates, through proper modeling and estimation of the RF circuitry impulse responses.
Proceedings Article
Relative channel reciprocity calibration in MIMO/TDD systems
TL;DR: It is demonstrated that in a single-user MIMO channel and for low signal-to-noise (SNR) ratios, the relative calibration method can increase the capacity close to the theoretical limit.
