Exploiting Multipath Induced Diversity in OFDM Systems

Overview Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier block modulation scheme suitable for wireless communications. It is primarily used in high bit rate systems to mitigate inter-symbol interference (ISI) caused due to de- lay spread. While the ISI caused by delay spread is an annoyance factor, it also provides path diversity advantage if the path gains fade independently. This paper proposes a novel technique to exploit this multipath induced diversity in OFDM systems.

Radioactive: Bluetooth - survival of the fastest

The opposing technology approaches are orthogonal frequency division multiplexing (OFDM) and direct sequence (DS)-UWB. This increases the signal's range by reducing interference. The first work was the development of what was then called impulse...

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).
