Abstract:
The present application discloses a diversity receiver and a terminal. The diversity receiver includes a first main channel and a first diversity channel, the first main channel includes an antenna diplexer and a first main transmission channel, and the first diversity channel includes a tunable bandpass filter and a first diversity receiving channel. The first diversity receiving channel is coupled to a diversity antenna by using the tunable bandpass filter, and the tunable bandpass filter is configured to: adjust a passband bandwidth of the tunable bandpass filter according to a band bandwidth of a first transmit signal generated by the first main transmission channel and a band bandwidth of a first receive signal received from the diversity antenna, and perform bandpass filtering based on the passband bandwidth on the first receive signal.

Claim (Index 8):
The diversity receiver according to  claim 6 , wherein the adaptive filter is configured to:\n use the first baseband signal as a reference signal, synchronize the reference signal with the second baseband signal, and construct the IMD2 interference signal according to the following formula: IMD \ue89e \ue89e 2 = \u2211 i = 1 n \ue89e S i \ue8a0 ( I i 2 + Q i 2 ) + \u2211 i = 1 , j = 1 n \ue89e C ij \ue8a0 ( I i \ue89e I j + Q i \ue89e Q j ) + \u2211 i = 1 , j = 1 n \ue89e nC ij \ue8a0 ( I i \ue89e I j - Q i \ue89e Q j ) + D \ue89e \ue89e C , IMD2 represents the constructed IMD2 interference signal, I i  represents an i-order in-phase component of the reference signal obtained after the synchronization, Q i  represents an i-order quadrature component of the reference signal obtained after the synchronization, I j  represents a j-order in-phase component of the reference signal obtained after the synchronization, Q j  represents a j-order quadrature component of the reference signal obtained after the synchronization, S i  is an autocorrelation coefficient, C ij  is a cross coefficient, nC ij  is a negative cross coefficient, and DC represents a direct current term, wherein i and j are natural numbers, i\u2264n, j\u2264n, and i\u2260j.
