摘要： 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.

摘要： A method and system for link adaptation between a wireless multi-carrier access point (102) and a wireless multi-carrier communication device (104) is described. The wireless multi-carrier access point obtains a set of available LEP methods from the wireless multi-carrier communication device. The wireless multi-carrier access point selects an LEP method from the set of available LEP methods, based on at least one link parameter. The wireless multi-carrier access point then communicates the LEP method selected, to the wireless multi-carrier communication device.

摘要： An Orthogonal Frequency Division Multiplexing, OFDM, transmitter comprises a signalling data generator (113) which generates a set of data symbols indicative of physical layer characteristics of data transmissions from the OFDM transmitter (100). A first symbol generator (115) and second symbol generator (117) generates a first and second OFDM signalling symbol by allocating the set of data symbols to subcarriers. The allocation of the physical layer data symbols to subcarriers is different for the first OFDM signalling symbol and the second OFDM signalling symbol. A data packet generator (105) and transmitter (101) generate a data packet and transmit this to an OFDM receiver (300). The OFDM receiver (300) determines the physical layer data symbols by combining the data symbols of corresponding subcarriers of the first and second OFDM signalling symbols and uses the resulting information to decode the user data of the data packet.

摘要： A transmitter comprises a block generator (109) which divides a data symbol stream into data symbol blocks. A divide processor (111) divides each block into a first set of data symbols stored in a first set buffer (113) and a second set of data symbols stored in a second set buffer (115). A space time block encoder (117) codes the first set in accordance with a space time block code to generate a coded set of data symbols. A parallel processor (119) then creates a plurality of parallel data streams from the coded set and the second set. Each of the parallel data streams is allocated to one of a plurality of antennas (129-135). A plurality of parallel stream transmitters (121-127) transmits the parallel data streams in parallel in a communication channel from the plurality of transmit antennas (129-135).

摘要： 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 (xI(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 (RI) with a limited number of the reproduced sub-carrier signals (RI-Rk) according to respective frequency offset coefficient (I, k) that is a function of an estimated value of the offset (fc) of the reference frequency relative to the carrier frequency.
