Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the signal points to other positions in the space diagram expressed at least in the polar coordinate system. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into, low and high, frequency band components which are designated as a first and a second data streams respectively. Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability. Furthermore, a communication system based on an OFDM system is utilized for data transmission of a plurality of subchannels, wherein the subchannels are differentiated by changing the length of a guardtime slot or a carrier wave interval of a symbol transmission time slot, or changing the transmission electric power of the carrier.

Abstract: An object of the present invention is to provide a test apparatus for testing a DNA substrate on which a plurality of DNA fragments for testing are arranged, wherein absolute precision is not required. The above-described problem was solved by providing a substrate on which a plurality of biomolecule spots containing a group of biomolecules (e. g., DNA, etc.) of a specific type are formed, where the pattern or position of the DNA spot is changed depending on specific data so that information of the specific data is recorded on the substrate.

Abstract: In the transmitter side, data are divided into two or more groups, according to importance. In a three groups system, for example, the data streams are then mapped onto a multiresolution constellation (QAM or modified PSK) in the following way. The most important data determine the quadrant, the next most important determine which of four subsets is used in the quadrant, and the least important determine which point is used within that subset. This mapping system allows receivers of differing capabilities to detect as much data as they are able, or a single receiver to detect as much data as the channel quality allows. For example, a QPSK receiver could detect the most important data, a modified 16QAM receiver could detect the most important and second most important data, while a modified 64QAM receiver could receive all the data. Furthermore, in an OFDM system, multiresolution transmission is provided by using long guard times and/or wider channel spacing (equivalently, longer symbols) for the more important data. A system using n-level VSB is also described.
