Abstract:In Time Division Duplex (TDD) Fixed Broadband Wireless Access networks, co-channel interference that arises from the correlation of downlink and uplink signals in different sectors may considerably degrade the spectral efficiency. To overcome the complexity and costs of complete frame-TDD boundary synchronization in the network, a combined Channel Assignment (CA) and Antenna Array (AA) approach is proposed to mitigate interference. First a RotatedInterleaved CA (RICA) scheme is applied, which exploits sector a… Show more
