Adaptation of Multiple Access Parameters in Time Hopping UWB Cluster Based Wireless Sensor Networks
White Paper Conventional systems assign identical multiple access parameters to all users regardless of the signal-to-interference plus noise ratio of the received signal. In this paper an adaptive assignment scheme for multiple access parameters in cluster... [23 Aug 2007]
Architecting a High-Capacity Last-Mile Wireless Mesh Network
White Paper This substantially reduces the bandwidth available to each node due to interference between successive hops on the same path as well as between neighboring paths. As a result, conventional single-channel ad hoc network architecture can not be... [19 Aug 2007]
Multi-Code Multicarrier CDMA: Performance Analysis
White Paper The bit error rate of the system is analytically derived in frequency selective fading, with Gaussian noise and multiple access interference. A novel multi-code multicarrier code division multiple access (MC-MC-CDMA) system is proposed and analyzed... [04 Jul 2007]
