Technologies to improve throughput in wireless multiple-input-multiple-output (MIMO) and single-input-single-output (SISO) systems are described. A first device includes a baseband processor with an Orthogonal Frequency Division Multiplexing (OFDM) circuitry that uses a digital multi-carrier modulation scheme that defines a set of data subcarriers, a set of pilot subcarriers, and a direct current (DC) subcarrier to communicate data in a wireless channel between the first device and a second device. The baseband processor also includes subcarrier pre-equalization logic that receives, from the second device, feedback data indicative of a frequency selective fading characteristic of the wireless channel and adjusts a first amplitude value of a subset of the set of data subcarriers to a second amplitude value. Adjusting the first amplitude value to the second amplitude value reduces the frequency selective fading characteristic of the wireless channel.
