Abstract: A data processing apparatus maps input symbols to be communicated onto a predetermined number of sub-carrier signals of an Orthogonal Frequency Division Multiplexed (OFDM) symbol. The data processor includes an interleaver memory which reads-in the predetermined number of data symbols for mapping onto the OFDM sub-carrier signals. The interleaver memory reads-out the data symbols on to the OFDM sub-carriers to effect the mapping, the read-out being in a different order than the read-in, the order being determined from a set of addresses, with the effect that the data symbols are interleaved on to the sub-carrier signals. The set of addresses are generated from an address generator which comprises a linear feedback shift register and a permutation circuit.

Abstract: A system and methods are provided whereby a user of a mobile device can adaptively switch the mobile device from speakerphone mode to handset mode without needing to look at the mobile device or without the need to activate a button or key sequence. In a preferred embodiment, modules are provided in the mobile device which allow for the detection of a voice conversation, the sampling of the user's voice and the switching between the two modes of operation. If the user's voice volume is above a certain threshold the mobile device operates in handset mode. If the user's voice volume is below a certain threshold the mobile device operates in handset mode. Through the inclusion of the embodiments described herein, a mobile device can allow a user to safely and quickly switch from one mode of operation to the other without a requirement for additional hardware in the mobile device.

Abstract: A receiver determines a symbol synch time for recovering data from a symbol of signal samples generated in accordance with Orthogonal Frequency Division Multiplexing. Each symbol includes a guard period which carries data repeated from a data bearing part of the symbol and pilot signal samples. The receiver compromises a pilot assisted tracker, a guard adapted filter processor and a filter controller. The controller is operable to excite the filter with the symbol signal samples to generate an output signal which provides a further representation of the channel impulse response. A symbol time adjustment estimator is operable to adjust the symbol synch time in accordance with the adjustment provided by at least one the pilot assisted tracker and the guard adapted filter processor. The pilot assisted tracker estimates the symbol synch time from a channel impulse response estimate generated from pilot signal samples.
