摘要： To provide high-quality communication even when the power for synchronization preamble is reduced in an OFDM communication system, an OFDM communication transmitter obtains a zero amplitude reduced preamble signal by passing a specified synchronization preamble through an ideal low-pass filter (10) to reduce a signal component near zero amplitude within a time domain, and time-multiplexes (11) the obtained zero amplitude reduced preamble signal with transmit data to generate an OFDM transmit signal. A receiver section (20) of the OFDM communication system determines the cross correlation (19) between a receive signal and a specified synchronization preamble (17), which is patterned the same as the counterpart in a transmitter section of the OFDM communication system, and detects a synchronization position in accordance with the determined cross correlation.

To achieve symbol synchronization, an OFDM communication device obtains a zero amplitude reduced preamble signal by passing a specified synchronization preamble through an ideal low-pass filter to reduce a signal component near zero amplitude within a time domain, and time-multiplexes the obtained zero amplitude reduced preamble signal with transmit data to generate an OFDM transmit signal.

摘要： An aqueous acid cleaning solution for aluminum metals which contains oxidized metal ions as an etching accelerator and does not contain hazardous fluorine and chromium ions. The solution contains an inorganic acid, oxidized metal ions, a chelate dispersant, if necessary a surfactant, and further an oxidizing agent for the metal ions reduced by cleaning. The dispersant has the effect of inhibiting the formation of a sludge from the oxidized metal, thus permitting the preparation of a sludge-free aqueous acid cleaning solution.
