High Data Rate MIMO-OFDM System With Orthogonal Delay Diversity Realization

Overview A high rate delayed space-frequency cyclic group code is proposed in this paper, which applies a new bandwidth and power-efficient space-frequency processing on the orthogonal-frequency-division-multiplexing (OFDM) system. The delayed orthogonality with respect to frequency tones among different transmitter antennas guarantees to exploit the full spatial and frequency diversity of the frequency-selective multi-input multi-output (MIMO) channel. In addition, after partitioning the subcarriers into groups and coding each group with the proposed block code, a maximized multiplexing gain can be obtained without any diversity loss. The proposed code can also be easily generalized to multiple transmitter antenna systems.

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).

Quocirca's Straight Talking: Wireless - who's ready to commit?

Understanding what has been holding up progress is therefore a key issue for both the mobile industry and customers who at the moment are not capitalising on their initial investment to exploit the potential of wireless remote access more fully.

Radioactive: Bluetooth - survival of the fastest

The opposing technology approaches are orthogonal frequency division multiplexing (OFDM) and direct sequence (DS)-UWB. The other approach sends out the signal in a single stream which reduces the complexity of the transmitter and the power it...

Peter Cochrane's Blog: More wireless equals more wires

The inclusion of more intelligent computing power will allow the use and reuse of both the physical and frequency space even more efficiently so we can access more than 100-fold the bandwidth we enjoy today.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?
