<P>PROBLEM TO BE SOLVED: To provide a data transmission/reception instrument and method of a wireless system which can improve performance by combining a control system of transmission power and an erasure error correction system. <P>SOLUTION: The data receiving device of this wireless system has a Q-ary encoding portion 10 which performs block coding of a data to be transmitted, a modulator portion 20 which modulates and outputs each Q-ary symbols outputted from Q-ary encoding portion 10, an amplifier portion 30 which amplifies and outputs each modulated and outputted data with the same amplification as target power to a channel gain. Further, the data receiver of this wireless system has a demodulation portion 100 which demodulates a signal received by each lower level channel and outputs Q-ary symbols, and a Q-ary decoder 200 which performs a block decoding to Q-ary symbols of each lower level channel outputted from the demodulation portion. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
