    摘要: Using midambles, tracking delay profile creator 107 opens correlation windows in the range of 8 chips before and behind the top path and creates delay profiles within this range. From the delay profiles, path determiner 108 detects whether or not there is a new path before the top path, and, when there is a new path, determines whether or not this is its path. Based on the result of the determination at path determiner 108, when the new path is its path, frame position controller 109 sets the top path with the new path. On the other hand, when the new path is not its path, the top path set earlier is retained as is as the top path. Then, in accordance with the timing of the top path set, a received signal is demodulated. By this means, reception quality can be improved.

    摘要: A pulse transmitter having a relatively simple structure and generating a pulse modulating signal even at a high transmission rate. In the pulse transmitter, a symbol pulse generating part (103) generates a symbol pulse of amplitude level β when data S1 is “0,” and that of amplitude level &ggr; when data S1 is “1” in the first pulse slot section, the data pulse generating part (104) generates a data pulse of amplitude level 0 when data S2 to Sn is “0,” and that of amplitude level α when data S2 to Sn is “1” in a later pulse slot section. The relationship of the amplitude levels keep the relation α

    摘要: A pulse signal reception device of a comparatively simple configuration detects a signal sampled at an optimal clock timing for a pulse modulation signal having a signal width shorter than a symbol frequency. In this device, a time division unit (103) samples a data signal at a clock signal rise edge and outputs the sampled data signals to counters (104-1 to 104-3), respectively. The counters (104-1 to 104-3) count the number of High levels when the data signal becomes High level within a predetermined period, and a maximum value detection unit (105) outputs maximum data string information on a data string counted by a counter in which the maximum number of High levels has been detected among the counters (104-1 to 104-3) to a selection data judgment unit (106). The selection data judgment unit (106) judges which data string sampled at a particular timing is to be selected as a demodulation data string.

    摘要: A received pulse signal based on an on-off keying modulation scheme is alternately sampled by AD conversion sections operated by a clock signal whose frequency is one-half of a transmission rate. In the synchronization, amounts of delay in sampling timing adjustment sections are made different from each other, whereby phases of two different points in a symbol pulse are sampled. An amount of delay in a variable delay section is adjusted in accordance with a result of comparison of the sampled values, thereby achieving synchronization. At the time of demodulation, the amount of delay in the variable delay section is held, and the amounts of delay in the sampling timing adjustment sections are switched to the same value, and the symbol pulse is alternately sampled. The sampled values are subjected to threshold value determination, and the determination result is subjected to parallel-to-serial conversion, whereby a demodulation output is acquired.
