Each reception path (1to N) receives an input of a data stream, corresponding to a modulated signal and embodied to provide a confidence index (CSIi) and an equalized data stream (Zi) from the received data stream. Said device is characterised in that the reception paths (1 to N) comprises a calculation module (24i) embodied to deliver a combined confidence index (CCSIi) and a combined data stream (CZi), from said confidence index (CSIi) and said equalised data stream (CZi) for the preceding path. The decoder (30) with weighted inputs is embodied to only process the combined confidence index (CCSIi) and the combined data stream (CZi), provided by the calculation module (24N) in the last path (N). The above particularly finds application in the reception of multi-channel signals for hertzian digital television.

Abstract: A timing recovery circuit in a QAM demodulator which uses a symbol rate continuously adaptive interpolation filter. The method of interpolation used in the present invention is defined as a function of time per interpolation interval, rather than as a function of time per sampling interval as is commonly implemented in the prior art. This allows the interpolation filtering to be totally independent of the symbol rate in terms of complexity and performance and provides a better rejection of adjacent channels, since the interpolator rejects most of the signal outside the bandwidth of the received channel.

Abstract: A quadrature amplitude modulation type demodulator having a dual bit error rate estimator unit that allows for high bit error rate measurements. The dual bit error rate estimator circuit uses information pertaining to the number of corrected bytes from a forward error correction decoder and the count of recognizable patterns of the frame over a sufficiently large number of frames. The two pieces of information can be compared at the bit error rate levels, where both the pattern recognition counter and the FEC decoder are able to output valid data. A comparison between the two pieces of information provides a way to detect the type of noise which occurs on the network and makes it easier to correct problems in signal transmission.

Abstract: A quadrature amplitude modulation (QAM) type demodulator having a pair of direct digital synthesizer (DDS) circuits. The first DDS circuit is located in a baseband conversion circuit before a receive filter and digitally tunes the signal within the receive filter bandwidth. The second DDS circuit is within a carrier recovery circuit located after the receive filter and serves to fine tune the signal phase.

Abstract: A QAM demodulator having a carrier recovery circuit that includes a phase estimation circuit and an additive noise estimation circuit which produces an estimation of the residual phase noise and additive noise viewed by the QAM demodulator. The phase noise estimation is based on the least mean square error between the QAM symbol decided by a symbol decision circuit and the received QAM symbol. The additive noise estimation is based on the same error as in the phase noise estimation, except that it is based only on QAM symbols having the minimum amplitude on the I and Q coordinates. The additive noise estimation is not dependent on the phase of the signal, thus, is independent of the phase noise estimator.

Abstract: A QAM demodulator having a first automatic gain control circuit which outputs a first signal that is a function of the received signal, the first signal being used to control the gain of an amplifier which supplies the input of an A/D converter, and a second automatic gain controller which outputs a second signal derived from the QAM circuit after filtering, the second signal controlling the gain of a digital multiplier which produces a signal which feeds into a equalizer by way of a receive filter. The dual automatic gain control circuits, situated before and after the receive filters, allow for better resistance to non-linearity caused by signals in adjacent channels. Additionally, the dual automatic gain control circuits allow for the amplification level of the signal to be limited before the demodulator to eliminate signal distortion and to be set to the correct level internally with digital gain. Also, there is no saturation of the A/D converter since there is no QAM feedback to analog circuits.
