Optimal Power Allocation in Multiuser OFDM Systems

Overview Multiuser orthogonal frequency division multiplexing (MU-OFDM) is a promising technique for achieving high downlink capacities in future cellular systems. A key issue in MU-OFDM is the allocation of the OFDM subcarriers and power among users sharing the channel. Previous allocation algorithms cannot ensure fairness in advance. In this paper, a proportional rate adaptive resource allocation method for MUOFDM is proposed.

TI's 'turbo Wi-Fi' - still born?

In the 802.11g standards battle, PBCC eventually lost ground to OFDM, or Orthogonal Frequency Division Multiplexing, as the modem of choice. The technique TI uses to boost turbo Wi-Fi's speed is known as PBCC (Packet Binary Convolutional Coding).

Radioactive: Bluetooth - survival of the fastest

The opposing technology approaches are orthogonal frequency division multiplexing (OFDM) and direct sequence (DS)-UWB. The former method, backed by Intel, is more complex: it chops up the signal and sends it over multiple frequency bands.
