摘要： A method and device is provided for detecting data symbols in a received radio signal. Each data symbol is allocated transmit-side a symbol value-specific PN sequence of successive PN chips in the chip clock, and the allocated PN sequences are offset QPSK modulated. The method for incoherent detection includes converting the received radio signal into a complex baseband signal sampled in the chip clock, generating a demodulated signal by differential demodulation of the complex baseband signal, calculating correlation results by correlating the demodulated signal with the derived sequences, and deriving the values of the data symbols by evaluating the correlation results. Each derived sequence is assigned to a PN sequence allocable transmit-side and includes derived chips, whose values correspond to a logic linking of particular PN chips of the PN sequence allocable transmit-side that is assigned the derived sequence. The invention relates furthermore to a corresponding receiving unit.

摘要： A transmitter-receiver circuit and a method for distance measurement between a first node and a second node of a radio network is provided, wherein a mode of the first node and a mode of the second node are switched from a normal mode for communication in the radio network to a mode for distance measurement, wherein, in the mode for distance measurement for a transit time measurement, a radio signal is transmitted by the first node and received by the second node and a radio signal is transmitted by the second node and received by the first node and a first distance value is determined by measuring the transit time of the radio signals. In the mode for distance measurement, for a phase measurement an unmodulated carrier signal is transmitted as a radio signal by the first node and received by the second node and an unmodulated carrier signal is transmitted as a radio signal by the second node and received by the first node and a second distance value is determined by measurement and calculation from four values of the phases for different frequencies of the radio signals. Whereby, the distance between the first node and the second node is calculated from the first distance value of the transit time measurement and the second distance value of the phase measurement.

摘要： A phase error corrector circuit and method are disclosed. In one embodiment, a phase error corrector circuit delays a PSK modulated signal and multiplies the delayed PSK modulated signal by the PSK modulated signal in order to generate a forward phase correction signal. The input signal is then mixed with the forward phase correction signal. In another embodiment, a phase error corrector circuit calculates a forward phase offset of a complex PSK modulated signal. The complex PSK modulated signal is phase shifted in a mixer by a phase difference offset in order to generate a phase corrected signal. A backward phase correction means calculates a backward phase offset based on the phase corrected signal. A subtractor subtracts the forward phase offset from the backward phase offset for outputting a difference phase offset to the mixer.

摘要： The invention discloses a method for determining the occupancy of a transmission channel with the help of a differentially demodulated signal, which was generated transmitter-side with the use of PN sequences from a PN sequence set, which has a first group of first PN sequences and a second group of second PN sequences, wherein the first and second PN sequences within their respective group differ from one another in a cyclic shift of their chip values and wherein the second group has for each first PN sequence a corresponding second PN sequence, which differs from the first PN sequence in an inversion of every second chip value. The method of the invention provides for a) the provision of at least two subsequences of an initial code sequence, which is assigned to one of the first PN sequences and can be derived from said sequence by logical operations, but is not identical to it, b) the calculation of at least two correlation results by correlating the differentially demodulated signal with each of the at least two subsequences, and c) the evaluation of the correlation results and generation of an output signal to indicate the occupancy of the transmission channel depending on the evaluated correlation results. The invention relates furthermore to a corresponding device for determining the occupancy of a transmission channel.

摘要： A complementary code decoder technique is provided where the encoded input data is first parallelized. From the parallelized data, correlation values are generated by a correlator circuit that is capable of changing its correlation characteristics depending on at least one control signal. Different control signals are sequentially provided to the correlator circuit thereby driving the correlator circuit to sequentially generate multiple correlation values from the parallelized data, based on different correlation characteristics. From the multiple correlation values, the correlation value that represents the optimum correlation is identified. This technique significantly reduces the gate count of the decoder structure, thus saving chip area and manufacturing costs.
