Claim 4:
5. The method according to claim 4, wherein:
an amplitude of a first spatial-frequency combination coefficient is a product of a reference amplitude and a differential amplitude;
the reference amplitude is a largest value of quantized amplitudes of spatial-frequency combination coefficients, in a first polarization direction, corresponding to the first spatial domain beam basis vector;
the differential amplitude is a ratio of a quantized amplitude of the first spatial-frequency combination coefficient to the reference amplitude;
the first spatial-frequency combination coefficient is any one of the spatial-frequency combination coefficients, in the first polarization direction, corresponding to the first spatial domain beam basis vector; and
the first polarization direction is any one of polarization directions of the first spatial domain beam basis vector.
