Abstract
The embodiments of the disclosure disclose a method and an apparatus for acquiring estimated values of transmitted signals, and a system-on-chip. The method comprises: in response to the sequence number N of a current OFDM symbol between sequence numbers N1 and N2 that are sequence numbers of two adjacent OFDM symbols containing pilots, for each RE within the Nth OFDM symbol, instantaneously acquiring a channel estimation value Cof the RE by a linear interpolation method; extracting an FFT value of the ith RE from an FFT buffer unit, and based on a preset MIMO demodulation algorithm, performing computation on the Cand the FFT value of the ith RE, thereby obtaining an estimated value of transmitted signals fro on the ith RE within the Nth OFDM symbol. The embodiments of the disclosure can save SOC memory, reduce SOC chip cost, and enhance SOC information processing performance.
