摘要： Disclosed is a pre-equalizer, a vestigial sideband (VSB) transmission system using the pre-equalizer, and a VSB transmission method. A first transmit signal is stored in a first memory, and a pre-equalizer pre-equalizes the first transmit signal based on a set tap coefficient. A transmitter modulates the pre-equalized first transmit signal, and sends the modulated signal. The first transmit signal is fed back to a receiver, which demodulates the transmitted first transmit signal and stores the demodulated signal as the second transmit signal in a second memory. Subsequently, the pre-equalizer calculates a tap coefficient based on an error value as the difference between the first transmit signal and the second transmit signal, and updates the set tap coefficient based on the calculated tap coefficient.

摘要： In an equalizer including a plurality of delay elements, a plurality of weighting elements and an adder, the impulse response of a signal transmission channel is estimated to selectively switch over a plurality of selector switches associated with the inputs and outputs of the respective delay elements, thereby selectively changing the combination of the delay elements and the weighting elements transmitting an input signal from the channel to the adder and also changing the combination of the adder and a delay element feeding back the output of the discriminator to the adder. Thus, the number of required taps of the equalizer can be reduced, so that the power consumption and size of the equalizer can be reduced.

摘要： In a decision-feedback equalizer for use in combination with a demodulator (13) to equalize a demodulated signal into an equalized signal through first and second transversal filters (15, 16), the demodulated signal and an input signal are filtered by the first and the second transversal filters into the first and the second filtered signals in accordance with a plurality of main controllable tap gains and a plurality of subsidiary controllable tap gains, respectively. The input signal supplied to the second transversal filter is controlled or selected by a supplying circuit (42). Specifically, the supplying circuit (42) produces as the input signal a first local signal obtained from the demodulated signal when the demodulator is put in a synchronization state. The supplying circuit produces as the input signal a second local signal obtained from the equalized signal when the demodulator is put out of the synchronization state.

摘要： An equalization filter is provided with the ability to softly switch between pure linear equalization and decision feedback equalization. A reliability gain factor and an associated gain factor calculated by a predetermined mapping relation are provided in a decision feedback path and a feedforward path, respectively. Increasing the reliability gain factor increases the significance of the decision feedback filtering. Better performance than pure linear equalization and pure decision feedback equalization can be achieved.

摘要： For providing a module for use of a mobile communication terminal, being small in sizes and high in reliability, and enabling with plural numbers of bands, and also a mobile communication terminal with using the same therein, canceling is conducted on transmission signal and/or noises of reception band on reception side with using a feed forward technology, for maintaining a degree of suppression of the transmission signal and/or the noises of reception band on the reception side. In this case, for achieving the cancellation of wide band signals from the transmission signal to the reception band, a delay adjusting function is used, in addition to gain and phase adjusting functions. Also, for conducting stable canceling of jamming signals, controls are conducted on the gain, the phase and the delay of a loop with using a reception SN and/or a CQI signal, etc.Further, for achieving low power consumption, a feed forward loop can be made ON/OFF depending on a level of the transmission signal.
