Abstract: A receiver path comprises a means for generating first digitized samples from a received analog signal at a first sampling rate, e.g. an ADC (12). An interpolating filter (13) is used to generate from the first digitized samples second digitized samples which are estimates of samples obtainable by sampling the received analog signal at a second sample rate lower than the first sampling rate, second digitized samples being output at the first sampling rate and including at least one unusable sample. A circuit (14) is provided for generating a signal for controlling components of the receive path downstream of the interpolation filter to prevent processing of the unusable sample. The advantage of this arrangement is that a separate oscillator at the second sampling rate is not required while still allowing the second sampling rate to be a whole multiple of 1MHz.

Abstract: A receive path in a receiver comprises means for deriving a first stream of first digitized samples from a received analog signal at a first sampling rate (12), and at least one interpolating filter (32,34,36) in parallel with the first stream of first digitized samples for generating at least a second stream of digitized samples at the first sampling rate but offset with respect to the first stream by a fraction of a sample time period from the first stream. This provides the advantage that a higher sample granularity can be obtained without increasing the sample rate.

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.

Abstract: Method and apparatus for a wireless receiver are described which derive at least a first stream of first digitized samples (30) from a received analog signal at a first sampling rate and identify a first frequency offset of the first stream based on a plurality of parallel correlations (40) using complex reference signals (38) which differ from each other by phase offsets. A second frequency offset is identified (48) based on tracking a demodulation accuracy for each symbol which is demodulated from the first stream of digitized samples. These frequency offsets can be used to rotate decision areas in the demodulator.
The methods and apparatus may be used in a Bluetooth receiver.

Abstract: A receiver comprises:
means (12) for deriving at least a first stream (30) of first digitized samples from a received analog signal at a first sampling rate, means (40,42) for selecting a first sampling point and at least a second sampling point,
a demodulator (44) for demodulating first and second symbols from the at least first stream of samples based on the first and the at least one second sampling points, and
means (46) for determining a value related to a demodulation accuracy for the first and second symbols and for outputting a signal, the means (40,42) for selecting being adapted to alter the sampling point based on the signal. By assessing the demodulation accuracy in real time clock drift can be compensated.
The demodulation accuracy can be a value related to a phase error or an error energy such as EVM or DEVM for each demodulated symbol.

Abstract: First and second wireless transceiver units (TX1, TX2) operate in the same portion of the RF spectrum. An arbitration device (130) controls when the first and second wireless transceiver units (TX1, TX2) can operate. An interface (151-154) connects the first transceiver unit (TX1) to the arbitration device (130) and receives requests for operation. The interface permits the transceiver unit (TX1) to use one of N possible priority levels (e.g. N=2) for requests. The transceiver (TX1) associates a transceiver priority level to a series of packets which is chosen from a range of M possible priority levels (where M>N, e.g. M=8). The transceiver unit (TX1) sends a sequence of requests to operate to the arbitration device, each request in the sequence having a priority level chosen from the range of N possible priority levels. The average value of the priority levels used in the sequence depends on the associated transceiver priority level.
