An assessment of interference cancellation applied to BWA

It is a general principle that a communication system should be designed to avoid interference in the first place, either through network planning or with effective radio resource management and medium access control. However to meet the increasing demands placed upon the radio spectrum, more efficient use is required and stringent requirements on interference levels can lead to large co-channel re-use distances in some radio systems. This paper assesses the effectiveness of interference cancellation techniques applied in an urban broadband wireless access (BWA) scenario. This demonstrates that greater coverage and throughput can be achieved in interference limited scenarios. Large gains were achieved with omnidirectional antennas, which is pertinent for mobile systems
