- A crucial challenge in the implementation of distributed massive multiple-input multiple-output (MIMO) architectures is to provide phase coherence while, at the same time, limit the complexity of the remote-radio heads (RRHs), which is important for cost-efficient scalability. To address this challenge, we present in this paper a phase-coherent distributed MIMO architecture, based on off-the-shelf, low-cost components. In the proposed architecture, up- and down-conversion are carried out at the central unit (CU). The RRHs are connected to the CU by means of optical fibers carrying oversampled radio-frequency (RF) 1-bit signals. In the downlink, the 1-bit signal is generated via sigma-delta modulation. At the RRH, the RF signal is recovered from the 1-bit signal through a bandpass filter and a power amplifier, and then fed to an antenna. In the uplink, the 1-bit signal is generated by a comparator whose inputs are the low-noise-amplified received RF signal and a suitably designed dither signal. The performance of the proposed architecture is evaluated with satisfactory results both via simulation and measurements from a testbed.

Technology Transfer Offices, Incubators, and Intellectual Property Management

Konferensbidrag (refereegranskat)abstract
- In this paper we present a systematic literature review of the intersection between intellectual property (IP) management, technology transfer offices (TTOs) and incubators (and to some degree also science parks) in order to find out how incubators and/or TTOs support and work with patenting and IP management in startups. IP management is an important issue for the competitiveness of technology based startups and a difficult issue due to the resources needed to obtain, monitor and enforce IP rights. Understanding how the support organizations facilitate this work is therefore of importance for the startups as well as for universities and policy actors seeking to support technology transfer. The identified publications were systematized according to the actor in focus and whether the paper discussed IP as an output or as a strategic focus. The literature review showed that this literature tends to adopt a simplistic view of IP management, not taking all strategies into account. The literature typically narrows the focus down to a simplistic view of trying to increase the patent output of TTOs and incubators, and the related firms and/or universities.
