摘要： An input signal includes spread signals which are respectively transmitted over a plurality of channels. First and second despread demodulators demodulate the spread signals transmitted over first and second communications channels by despreading them with first and second spread codes, respectively. A path detector generates a timing signal for instructing the timing at which the despread demodulators perform the despread operation. The path detector is shared by the first and the second despread demodulators, and operates in a time-division manner.

摘要： The present invention relates to a circuit which controls the decision timing for deciding multi-level signal to the optimum decision timing. The control is carried out in such a manner as reducing deviation of phase of decision clock by deciding slope of multi-level signal at the center decision timing from the decision data at least continuous three decision timings and deciding deviation of decision timing from the slope and error signal at the center decision timing. Moreover, two kinds of slope decision are realized and the desired slope decision can be selected in accordance with the line condition.

摘要： The present invention relates to a radio transmission system. The system includes a transversal type automatic equalizer which controls tap weight based on bit error rate (BER) from a pseudo error pulse. In the equalizer, the threshold value (BER1) which defines the mode change for tap weighting control from normal to reset is different from the threshold value (BER2) from reset to normal. Therefore, the mode change is carried out by a simple circuit properly and stably.
