Abstract: A wireless transmitting apparatus capable of improving the reception error rate of a wireless receiving apparatus. In the inventive apparatus, a channel estimating part (122) acquires a propagation path estimated value. A control part (113) determines whether an estimation precision of the acquired propagation path estimated value is equal to or greater than a predetermined level. A pre-equalization (PE) part applies PE based on the acquired propagation path estimated value to a transport signal if it is determined that the estimation precision is equal to or greater than the predetermined level. Otherwise, the pre-equalization (PE) part avoids the PE application to the transport signal. An RF part (117) transmits the transport signal to which PE has been applied, and transmits the transport signal for which the PE application has been avoided.

Abstract: There is provided a radio transmission device capable of improving the system throughput in multi-carrier communication. The device includes IQ separation units (20-1 to 2O-K) for separating an I channel and a Q channel from the inputted symbol and inputting them into control units (22). The control units (22-1 to 22-K) reduce the power of the parity bit by reducing the amplitude of the channel corresponding to the parity bit among the I channel and Q channel inputted. IQ multiplexing units (24-1 to 24-K) multiplex the I channel and Q channel inputted from the control units (22-1 to 22-K) and return them to a symbol, which is inputted to an IFFT unit (26). The IFFT unit (26) subjects the symbol inputted from the IQ multiplexing units (24-1 to 24-K) to inverse fast Fourier transform (IFFT) and maps it to respective sub-carriers f1 to fK, thereby generating an OFDM symbol.

Abstract: A transmission apparatus capable of executing an appropriate transmission power control in DPCH even when the DSCH and DPCH are multiplexed together. In the present transmission apparatus, DPCH transmission power control section 105 controls the transmission power of dedicated channel so that transmission power in periods corresponding to packet insertion periods of downlink shared channel becomes larger than that in other periods. Amplification sections 104-1 to 104-N amplify the transmission power of dedicated channel based on the control of DPCH transmission power control section 105. Dedicated channel and downlink shared channel are multiplexed in multiplexing section 106. The multiplexed signal is converted into radio frequency in RF section 107, and then transmitted as radio signal from antenna 108.

Abstract: The fading correlation monitor 103 detects an angle spread of the communication terminal apparatus 200-1 and decides whether the angle spread has a larger or smaller relationship with a preset threshold value. When the estimated angle spread is smaller than the threshold value, the interference wave is suppressed by carrying out directive reception which is carried out by an AAA receiver 106 as well as performing directive transmission which is carried out in a transmitting circuit 122.While, when the estimated angle spread is larger than the predetermined value, the distortion of the signals due to the fading is compensated by carrying out diversity receiving which is carried out in a diversity receiver 107 as well as performing diversity transmission which is carried out in a diversity transmitter 123.On account of this, even when the fading correlation is small, it is possible to carry out a radio communication with a satisfactory communication quality.
