The invention provides a balance module and balance method for a receiver. The balance module comprises a feedforward part, a decision unit, an error calculation unit, a state control unit, coefficient updating units and a feedback part. Output signals of the receiver are shifted by data units and then are gated to multiplier adder units in sequence; the multiplier adder units carry out multiplication and accumulation on received data and a coefficient of the coefficient updating unit and then generate I-way sum and Q-way sum. The I-way sum and the Q-way sum are output to the error calculationunit as balanced values. Moreover, the I-way sum and the Q-way sum are output to the decision unit to generate decision values. Error calculation is carried out according to the decision values and the balanced values of the receiver. Products of errors and step sizes are calculated to obtain coefficient updating quantity, and a current coefficient is updated. Data generated by the multiplier adder units of the feedback part is taken as the updated balanced values, and the updating is carried out continuously. According to method, the chip space can be reduced and the circuit design difficulty and scale are reduced.
