A Low Complexity Antenna Diversity Receiver for OFDM Based Systems

Overview A low complexity antenna diversity architecture with a new combining technique suitable for Orthogonal Frequency Division (OFDM) based systems is introduced in this paper. For a two branch antenna diversity, this structure requires only one FFT at the receiver and allows optimum maximum ratio combining. For systems with a higher number of antennas, the number of required FFTs when using such technique is reduced by half as com-pared to the conventional case where a different FFT is used for each receive antenna. As a result a considerable reduction in processing complexity is obtained especially for systems with high number of subcarriers.

Tailless mice eating holes in corporate networks

This second receiver's range can only be extended to 30m with a larger antenna - so it wouldn't be that easy for the miscreant to hide themselves. The risk arises when Logitech's wireless mouse and keyboard, on start-up, try to synchronise with a...

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).
