AbstmctThis paper presents an adaptive tracking algorithm for adaptively updating the bit and power allocation for OFDM transmission in a time-varying channel. The proposed algorithm utilizes the previous bit allocation information for initialization, and then iteratively reflnes the allocation until it reaches the optimal solution. We prove a theorem which(More)
The use of implant-retained mandibular overdentures is a treatment option for compromised patients. The combination of using a bar and intracoronal attachments to connect two implants provides cross-arch stabilization, good retention and stability for the overdenture which is still mainly supported by soft tissue. However, connecting the component parts of(More)
