Patent CA-2316904-C (CA)
Title: Ofdm transmitting and receiving apparatus and ofdm transmitting and receiving method
Inventor: ISHIKAWA KIMIHIKO
IPC: H04L27/26
Filed: 1999-11-04
Granted: 2006-10-17
Abstract: A coefficient signal for each sub-carrier is calculated by calculating an average of receiving powers of sub-carriers (A to D) in a control circuit (162) and by dividing the average by an envelope of each sub-carrier (A to D). A transmission signal of each sub-carrier (A to D) output from each of relative mapping circuits (102 to 105) is multiplied by a coefficient signal in each multiplier (106 to 109), whereby powers received at sub-carriers are approximately uniformed to improve error rate characteristics.

Granted: 2007-07-10
Abstract: A network element for use in a heterogeneous telecommunications system employs "out of band" signalling to automatically discover the identity of the two ports connecting two network elements through a specific link. Either of the connected network elements may be a circuit switching network element or a packet switching network element. One network element initiates the port discovery process and transmits a SONET/SDH overhead signal to the network element attached at the other end of the link. The other network element monitors the status of its ports and, when it detects a change in state at one of the ports, resulting from the first network element's transmissions, the receiving, or passive, network element recognizes the port as the port which forms a part of the link of interest.

Abstract: A digital transmitter converts a digital signal into analog form with a digital to analog converter (DAC) and uses an analog signal image produced from the DAC  to provide an analog signal at a transmission frequency and/or uses a projected analog signal image to produce analog signals for transmission. Rather than removing analog signal images with a low pass filter at the output of the DAC and/or using analog signal images and analog mixers for frequency conversion, the digital transmitter uses the analog signal images from the DAC to produce the analog signals at the desired frequency/frequencies. By setting and/or adjusting the conversion rate for the DAC and/or the digital signal frequency/frequencies; the analog signal images produced from the DAC can be positioned in the desired frequency band(s). For example, the digital transmitter can position the digital signals within non-overlapping portions of a conversion bandwidth defined as one-half the conversion rate for the DAC. When the digital signals are converted into analog form, the DAC produces analog signal images periodically repeated at multiples of one-half the conversion rate such that analog signal images are produced at the appropriate frequency band(s) for amplification and transmission.

Title: The copy protection of digital audio compact discs
Inventor: HEYLEN RICHARD A A
IPC: G11B7/004
Filed: 2001-02-14
Granted: 2010-11-09
Abstract: The ability of a data reader, such as a CD-ROM drive, to access, extract, or otherwise read the data on a digital audio compact disc provides a problem for the music industry. A user can use his CD-ROM drive to read the data from an audio disc into a computer file, and then that data can be copied. To provide copy protection, errors are deliberately introduced into the data on a CD, but these errors are of a type which are generally transparent to an audio player but which will interfere with the reading of the audio data by a data reader. According to the standards, the data on a CD is encoded into frames by EFM (eight to fourteen modulation). Each frame has sync data, sub-code bits providing control and display symbols, data bits and parity bits, and includes 24 bytes of data, which is audio data for a CD-DA. The standard requires that 98 such frames are grouped into a sector. To provide copy protection, each sector is provided with a non-standard number of frames, for example, has 99 rather than 98 frames. Then the SO and S 1 sub-code synchronisation patterns are placed one frame later than they otherwise would be, but the data within each frame remains the same. An audio player would divide the 24 bytes of data from each frame of the sector into 4 byte samples and continue playing the disc, albeit with an inaccurate time display. Howewer, a data reader used to read audio data from the CD-DA to enable a copy to be made, would produce a copy having a degraded quality of sound.
