PDF TDMA in Adaptive Resonant Beam Charging for IoT Devices ... . The method can satisfy different data rate requirements among users with efficient resource utilization. In this algorithm, channel assignment and power allocation are operated separately. In this paper, we analyze the effects of these radio impairments in a multiuser SC-FDMA uplink system and present digital-signal-processing-based methods for the joint estimation and equalization of impairments and channel distortions on the receiver side with an arbitrary number of receiver antennas.

No. 60/553,779 filed on Mar. 16, 2004, the dis A receiver includes multi-user detection (MUD) functionality and a cognitive engine. The receiver may also be coupled to multiple antennas and have analog beamforming capability. The cognitive engine is operative for selecting a beam or beams associated with the multiple antennas to enable successful demodulation by the MUD. The receiver has application in multiple access channels and in other ... The spectrum efficiency is denoted as the average number of bits transmitted by a subcarrier, and the outage probability indicates the number of the OFDM symbols terminated due to insufficient data rate versus the total numbers of OFDM symbols simulated by the No. 4 LU Yan-hui, et al.: Adaptive radio resource allocation for multiple traffic OFDMA broadband wireless access system 5 method. A method processes information to be sent via radio, according to which first bits represent a first number of N-tuples and second bits represent a second number of N-tuples. The first bits are to be sent using a first group of sub-bands of a frequency band, and the second bits are to be sent using a second group of sub-bands of the frequency band.
