摘要： Disclosed is a spectrum spread communication system which is hardly influenced by noises, and in which a frame structure can be identified at a receiving side without use of a frame synchronization signal. A spread code generator switches spread codes (“Scai” and “Scbi”) in each frame, and outputs it to a spread modulation unit. The spread modulation unit performs spread modulation of transmission data, and transmits it to a direct current power line. A reference code generator generates reference codes (“Scai” and “Scbi”) in the same code phase. Spread demodulation units performs spread demodulation of the received signal with use of the reference codes (“Scai” and “Scbi”), and output it to a selection unit. A frame synchronization detection unit identifies a frame structure on the basis of switching of a synchronization state of a code phase in a code phase synchronization detection unit. The selection unit outputs reception data by selecting spread demodulated data from the spread demodulation unit which is in a phase-synchronized state.

摘要： Delay time between an input of data to a circuit block and an output of the data from the data block is measured in accordance with a timing at which the data from the circuit block is acquired by a measurement register and a timing at which the data from the circuit block is acquired by a data latch. An LSI tester sets well voltage adjustment values so that delay time of each circuit block is averaged. From voltages generated by the adjustment voltage generating circuit, a selector selects voltages that are in accordance with the well voltage adjustment values. The voltages selected are applied to a well of a CMOS transistor of each clock timing adjustment circuit. Delay time between timings of inputted clocks is thus adjusted.

摘要： A transmitting circuit 10 converts transmission data to a multilevel analog signal suitable for transmission. The multilevel analog signal is output to a cable 21 via an amplifier and a hybrid circuit 12. In the transmitting circuit 10, a waveform which compensates waveform deterioration at the cable 21 is generated. A reception signal from the cable 21 is input to a mixer 14 via the hybrid circuit 12 and an amplifier 13. The mixer 14 mixes the reception signal and a cancel signal output from a cancel signal generation circuit 17 so as to remove undesired signals. In a receiving circuit 15, the signal output from the mixer 14 is sampled by use of a plurality of sample-hold circuits, and subjected to analog sum-of-product computation which is performed by a matrix circuit for distortion compensation. Subsequently, the sampled signals are converted to digital signals. The digital signals are collectively subjected to processing such as parallel-serial conversion, whereby reception data and an evaluation signal are obtained. An adjustment control circuit 18 includes a CPU, and adjusts the respective circuits on the basis of the evaluation signal such that data can be correctly transmitted and received.
