Abstract: 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.

Abstract: Each transmitter (4) included in a first transmitter group (40A) transmits, on a first electric wire (2A), a current signal representing a change in current in accordance with a transmission bit sequence. Each transmitter (4) included in a second transmitter group (40B) transmits, on a second electric wire (2B) that is connected in parallel with the first electric wire, a current signal representing a change in current in accordance with a transmission bit sequence. A current detection unit (6A) outputs an electric signal representing a change in a difference current between a first current (IA) flowing through the first electric wire (2A) and a second current (IB) flowing through the second electric wire (2B). A receiver (5A) identifies and receives a reception bit sequence corresponding to the transmission bit sequence of each transmitter (4) included in the first and second transmitter groups, by processing the first electric signal.

Abstract: A serial-parallel converter/encoder unit 11 inputs a transmission symbol data at a transmission symbol rate that is one-Nth of a base-point symbol rate. A precoder/collator 13 creates a transmission symbol waveform at the base-point symbol rate. The transmission symbol waveform becomes a transmission signal after passing through a roll-off filter 14 with a band corresponding to the base-point symbol rate and a modulator 15. A reception signal demodulated by a demodulator 33 is input to a fractionally-spaced equalizer 38 that operates at the base-point symbol rate and is forcibly equalized at the transmission symbol rate by using a reference signal. A level of a signal output from the fractionally-spaced equalizer 38 at the transmission symbol rate is determined by a level determining unit 39 and becomes a reception symbol data by a sawtooth-function output unit 40.
