A multiple-input multiple-output (MIMO) receiver for Wireless Fidelity (Wi-Fi), and an electronic device. The MIMO receiver for Wi-Fi includes n antennas, an energy detection circuitry, a multilink gating circuitry, receiving links, a frequency offset adjustment circuitry, and a gating control circuitry. The multilink gating circuitry includes one energy detection gating output terminal coupled to the frequency offset adjustment circuitry through the energy detection circuitry and n−1 non-energy detection gating output terminals coupled to the frequency offset adjustment circuitry. The multilink gating circuitry connects each gating input terminal to one of the gating output terminals. The gating control circuitry periodically obtains a signal strength of each of the receiving links, and controls, based on the signal strength, the multilink gating circuitry to connect the gating input terminal corresponding to the receiving link that meets a preset condition to the energy detection gating output terminal.
