Object recognition via compressive sensing
- Ahn J.
When the compressive sensing theory is applied to compressive imaging of natural images, we get fewer non-pixel measurements instead of pixel values. We propose how to make the direct use of compressed measurements without time-consuming image recovery for object recognition. For this, we use an orderly-permuted Hadamard matrix as a ...
On Channel Estimation Performance in Multi-Cell TDD Systems
- Gacanin H.
- Ligata A.
In this paper, we analyze the bit error rate (BER) and mean square error (MSE) performance for data uplink of a multi-cell TDD system with imperfect knowledge of channel state information (CSI). We investigate the impact of imperfect CSI, channel tracking methods and pilot contamination on the achievable performance, and ...

The rise of ...
Compensation of Imperfections Caused by Digital Pulse Width Modulation Using Frequency Dependent Baseband Injection
- Yu X.
All-digital transmitter is a hot topic since a few years. One of the key elements of all-digital transmitters is the modulator, which modulates the baseband IQ signal onto a carrier frequency in the form of digital binary signals. The combination of delta-sigma modulation and pulse width modulation is a very ...

It also briefly presents the use cases on which the WP5 work will be based on and categorizes the solutions ...
Optimal fronthaul capacity allocation and training for joint uplink receiver in C-RAN
- Boviz D.
- Sheng Yang
In Cloud Radio Access Networks (C-RAN) one of the main challenges is accurate data transfer on limited capacity fronthaul links between Remote Radio Heads (RRHs) and the central processing unit. Particularly in large-band and multiantenna transmissions, fronthaul capacity can be a limiting factor. In this paper we study the impact ...
