This paper presents a path-loss prediction analysis and a performance evaluation of the 60GHz IEEE 802.11ad standard. Received signal strength measurements were performed in indoor locations and the decay coefficients were estimated over a number of measured routes. Furthermore, real world maps were incorporated into a 3-D mm wave ray- tracing tool for the purpose of employing realistic channel matrices...
This paper presents a practical demonstration of the benefits of limited feedback beamforming for mmWave applications. Different beamforming strategies are presented, analysed and compared. Compressive sensing (CS) is investigated to accurately estimate the sparse Power Angular Profile (PAP) of the mmWave channel. This information is then used to estimate the antenna array weights required to steer...
In this paper a 3D ray tracing tool is developed for mmWave outdoor environments. Coverage analysis and system performance is performed for a small cell system at 60GHz. Peak throughputs beyond 3Gbps and cell edge throughputs in excess of 500Mbps are demonstrated at 98% of the mobile test locations. Analogue codebook based beamforming is applied. The analysis of the statistical angular spread at the...
In this paper the use of compressive sensing (CS) to accurately estimate the sparse Power Angle Profile (PAP) of a mmWave propagation channel has been investigated. This scheme is especially attractive for outdoor mmWave applications where large antenna arrays are more likely to be deployed to compensate for high pathloss. Current analogue beamforming techniques such as the codebook based 802.11ad...
This paper analyses the potential of polarimetric filtering to mitigate interference in a 60 GHz WPAN. A 3D ray tracing model is developed to simulate realistic propagation scenarios in a dense indoor environment and a Received Bit Mutual Information Rate (RBIR) abstraction technique is used to evaluate link level performance. Subsequently, the spatial reuse gain and the fairness between users at...
A 2×2 60 GHz MIMO solution combined with polarisation diversity is proposed for high throughput WLAN applications. In addition to a PHY throughput of more than 12 Gbps, this scheme is robust against polarisation mismatch and antenna tilting due to the adoption of circular polarisation. It also offers the possibility to detect LOS/NLOS conditions for antenna adaptation. A fast beamforming ability that...
