Abstract: A wireless communication unit (4160) comprises a processor (508) having a power-aware link adaptation function (540) for selecting an operational mode of the wireless communication unit (460) to transmit at least one data packet, the wireless communication unit (460) characterised in that the processor (508) is configured to perform, or is operably coupled to, a communication medium monitoring function that monitors an occupancy of a communication medium that comprises a plurality of communication links and, in response to a determination of i-he occupancy of the communication medium, the processor (508) performs link adaptation for at least one data packet transmission of the wireless communication unit (460). In this manner, in the provision of a power-aware link adaptation concept together with a communication medium occupancy monitoring function one or more of several links sharing the same communication medium can be selected to minimise power consumption within the wireless communication unit.

Abstract: A receiver for an orthogonal frequency division multiplex radio signal in which a carrier frequency is modulated by sub-carrier signals (S1) coded with data. Analogue signal processing means (3 to 12) produces base-band analogue signals (I-Rx, Q-Rx) in phase quadrature and analogue-to-digital converters (13, 14) convert the analogue signals to phase quadrature digital signals (x1(n), xq(n)). The digital signal processor includes the OFDM demodulator (15) and mismatch compensation (17, 18). The mismatch compensation (17, 18) combines each of the reproduced sub-carrier signals (R1) with a limited number of the reproduced sub-carrier signals (R1-Rk) according to respective frequency offset coefficient (1, k) that is a function of an estimated value of the offset (fc) of the reference frequency relative to the carrier frequency.

Abstract: An apparatus for improving signal mismatch compensation between first and second RF signals comprises: at least one switch which applies a first RF signal, present on a first pathway, and a second RF signal, present on a second pathway, to respective first and second frequency mixers, during a first time period; the mixers provide a first pair of mixed first and second RF signals. Means for reversing the at least one switch, during a subsequent time period is provided so that the first RF signal is applied to the second mixer, via the second pathway, and the second RF signal is applied to the first mixer, via the first pathway. The mixers thereby provide a second pair of mixed first and second RF signals. Monitoring monitors respective first and second pairs of mixed RF signals during an interval. The monitoring means provides time averaged values for the first and second signals in each of said first and second pairs of RF signals, so that effects of signal mismatch on the first and second RF signals are minimised in each channel, by subjecting said RF signals in each channel, for substantially the same time, to the same pathways.
