摘要： The invention relates to a data transfer method and a data transfer system between a first and a second transceiver, the data transfer comprising transmitting a data signal from the first transceiver to the second transceiver in a broadband channel, measuring, at the second transceiver, the frequency response of the channel and the frequency response of the data signal from the received signal. Measurement results are compared with each other and a need for change in the frequency response of the data signal is determined on the basis of the comparison. Information about the need for change is transmitted to the first transceiver and the frequency response of the data signal to be transmitted is modified at the first transceiver on the basis of the information.

摘要： A spinal therapy apparatus including at least one gripping member whose direction deviates from the transverse direction relative to the spinal column, so that the angle between the gripping member and the midline of the spinal column is less than 90°. A gripping member unit includes preferably two gripping members the angle between the ridges of the gripping members being less than 180°. There is a gap or groove between the gripping members. The gripping member unit also includes a support part, the support part being padded, preferably including two parts and in an inclined position relative to the floor. There is a groove between the gripping member and the support part. The spinal therapy apparatus may also incorporate at least one support handle, which the user can use to move the required part of the spinal column to the ridges of the gripping members.

摘要： A digital communication system (20) in which a signal constellation (30) of a dimensionality of at least four is used, with distance properties chosen to reduce the bit error rate compared to that of digital communication systems using signal constellations of half the dimensionality. A symbol generator (21) uses the higher dimensional signal constellation (30), or any orthogonal transformation of the higher dimensional signal constellation (30), to translate a bit stream into a stream of higher dimensional symbols, which it then provides to a modulator (22). The modulator (22) transmits each higher dimensional symbol in at least two parts, using a modulation scheme according to the prior art, such as QAM or QPSK.
