Abstract: An equalizer for a multi carrier signal for carrying out equalization adapted to each carrier or group of carriers, Fourier transforms the multi carrier signal, and obtains difference terms of the multi carrier signal. Both are input to an adaptive filter, to output equalized signals, wherein decimation is applied to at least some of the difference terms input to the filter. This is notable for enabling the complexity to be reduced for a given performance level. In particular since only non-zero filter taps need to be stored and updated, coefficient memory and coefficient calculation capacity can be reduced. Another way to reduce complexity involves measuring noise for at least some of the carriers, and dynamically adapting the size of the filter on a per carrier basis according to global optimizion euristic algorithms which adapt this filter size based on the comparison between this noise and an optimal performance figure achieved in a previous ISI-ICI free measurement phase.

Abstract: In mobile, wireless communication systems the channel between the transmitter and receiver varies during a transmission. This is often referred to as fading, of which different kinds exist. Each resulting in different impairments with specific properties.
A low complexity scheme is described to reduce the noise created by inter-carrier interference or ICI. The method makes use of the guard interval and first order Taylor approximation of slow varying channel. It is not restricted to wireless communication and can be used in any environment with varying channels.

Abstract: The present invention discloses a system and a methodology for enhancing performance during wireless communications by reducing system latency, MIPS requirements and power consumption. The present invention discloses a system and method of wireless data communication in which part of upper layer stack processing is performed on a controller to relieve a host processor of some data intensive operations. After the initial connection establishment phase in which the controller retrieves certain information required for data transmission and stores the same locally, the data source provides data directly to the controller without routing the data through the host. The host is relieved of the data processing that needs to be done while the data is being transferred. Hence, the overall latency of the system is improved because of the optimal routing of data traffic. The host can even go to lower power modes while the controller is performing the data operations on behalf of the upper layer stack thereby saving power consumption of the overall system.

Abstract: A device has a radio transmitter (10) for a first radio link such as a Bluetooth link, having a coexistence controller (60) arranged to communicate with a co located other radio transmitter (30) for another radio link, to enable both radio links to use potentially conflicting transmission frequencies. A link monitor (50) monitors the first radio link, according to an output from the coexistence controller. By making the link monitor dependent on the coexistence controller, it can distinguish between transmission losses caused by the coexistence interface, and those caused by other effects, to reduce the risk of a data rate controller unnecessarily reducing a transmission rate if transmission losses caused by the coexistence control are misinterpreted as a drop in link quality.
