The invention discloses a method for treating radioactive wastewater. The method for treating the radioactive wastewater comprises the steps of firstly carrying out reverse osmosis treatment on the radioactive wastewater, then enabling the radioactive wastewater to enter a continuous electrodeionization unit to be treated, and further removing radionuclide so as to enable treated wastewater to reach discharge requirements; and respectively filling different mixed ion exchange resin in a plain water chamber and a thick water chamber in a continuous electrodeionization membrane stack of the continuous electrodeionization unit, wherein mixed ion exchange resin filled in the plain water chamber comprises, by volume ratio, 30%-60% of strong-acid cation exchange resin, 40%-60% of strong-base anion exchange resin, and 0%-30% of weak-base anion exchange resin, mixed ion exchange resin filled in the thick water chamber comprises, by volume ratio, 20%-50% of strong-acid cation exchange resin, and the balance strong-base anion exchange resin. A weak dissociation polymer portion is used for improving selectivity of continuous electrodeionization membrane stack to trace amount radionuclide, radionuclide with extremely concentration can be effectively removed, and the method for treating the radioactive wastewater ensures that the final discharged water satisfies the discharge requirements.

A transceiver for orthogonal frequency division multiplex communication has a transmitter module (1) and a receiver module (2). The transmitter (1) has an I-path (3) and a Q-path (4) to receive signals on a number of subcarriers provided by a signal generator (9). The receiver module (2) has a receiver I-path (7) and a receiver Q-path (8) to deliver signals to a processor (15). IQ imbalance is calculated for each of the transmitter and receiver by the signal generator sending a sample signal (XI(k), XQ(k)) over a one of the transmitter paths. The signal is then applied to one or each of the inputs to the receiver paths (7,8) to generate receiver output signals YI(k), YQ(k), RQ(k). The processor (15) is responsive to the output signals to calculate the transmitter and receiver IQ imbalance for that subcarrier. A calibrator (19) and compensator (20) are responsive to the calculated IQ imbalance to correct or compensate each subcarrier of the transceiver band.

When cancelling interference in a radio communication device for repeatedly decoding / receiving a spatially multiplexed signal, if a symbol of erroneous judgment is contained or if an error factor caused by a propagation channel estimation error or hardware error (carrier frequency error, sampling frequency error) is contained, reception characteristic is degraded by an interference signal component. The radio communication device (100) includes an error estimation unit (13) for estimating an error of a replica signal during interference cancelling and a weighting unit (14) for weighting likelihood information for a spatially multiplexed signal which is demultiplexed and multiplexed after the interference cancelling. Accordingly, even if an error of the replica signal during interference cancelling is contained, it is possible to obtain preferable reception characteristic.
