    摘要: A wireless transmitter and receiver increase a desired/unwanted (D/U) ratio of a correlation output without increasing the number of data in an ultra-wideband direct spread pulse communication system for transmitting and receiving two series of data through different spreading code streams. In the spreading codes used in matched filters of the wireless transmitter, (2*N−2)-th and (2*N)-th values of a cross-correlation signal between first and second spreading codes are greater than 0, (2*N−3)-th and (2*N+1)-th values of an auto-correlation signal of the first spreading code are less than 0, and (2*N−3)-th and (2*N+1)-th values of an auto-correlation signal of the second spreading code are less than 0. The peak value of the cross-correlation signal does not need to be small, and since a value other than the peak value does not become large, the D/U ratio can increase.

    摘要: A complex coefficient transversal filter using a SAW filter and a complex frequency converter using the complex coefficient transversal filter are provided, in which a first SAW filter receives a real signal as an input signal and generates a real component of a complex signal, and a second SAW filter receives the real signal as an input signal and generates an imaginary component of the complex signal. Accordingly, feed-through waves between the input and output stages can be cancelled, and a phase difference between real and imaginary signals can be maintained at 90° without a phase shift. In addition, when a low-IF frequency converter is implemented using the complex coefficient transversal filter, an image suppression characteristic is improved. When a zero-IF frequency converter is implemented using the complex coefficient transversal filter, an error vector magnitude (EVM) characteristic is improved.

    摘要: Not only is it possible to let the viewers watch information that an information provider wants watched by the viewers in a reliable manner, but it is also possible to provide the viewers with information that the information provider desires. A content providing server 1 appends an encryption key ID of an encryption key used when encrypting content data to the content data encrypted using the encryption key and transmits the content data appended with the encryption key ID to a content reproduction device 3, while it transmits the encryption key to a CM providing server 2. The CM providing server 2 embeds the encryption key into CM data and transmits the CM data in which is embedded the encryption key corresponding to the encryption key ID that has been received from the content reproduction device 3 to the content reproduction device 3. The content reproduction device 3 transmits the encryption key ID to the CM providing server 2 and reproduces the CM data received from the CM providing server 2 to decrypt the content data using the encryption key embedded in the CM data, after which it reproduces the decrypted content data.
