OFDM Systems With Both Transmitter and Receiver IQ Imbalances

Overview The implementation of OFDM-based systems suffers from impairments such as In-phase and Quadrature-phase (IQ) imbalances in the front-end analog processing. Such imbalances are caused by the analog processing of the Radio Frequency (FS) signal and can be present at both the transmitter and receiver. The resulting IQ distortion limits the achievable operating SNR at the receiver and the achievable data rates. In this paper, the effect of both the transmitter and receiver IQ imbalances in an OFDM system is studied and algorithms are developed to compensate for such distortions.

BT to offer wireless networking for SMEs

Each device is fitted with a transmitter/receiver, which then allows it to communicate with a main controller or base station. There will be no problem because we have 120 available channels to run from with 10 different frequency," he said.

Peter Cochrane's Uncommon Sense: Chips in everything

So, as a customer gets to a checkout, the beam energises both receiver and transmitter components, and product information is sent to the register. The next phase already has some manufacturers embedding RFID (Radio Frequency IDentification) tags...

Peter Cochrane's Uncommon Sense: Wireless everything

The interference problem was gross as the nearest transmitter to your receiver dominated. We can create complex digital signals that occupy a broad swath of frequency space and still filter them out at the receiver.

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
