A mobile device includes a receiver configured to perform hybrid precoding on signals received through a large bandwidth communication. The receiver includes a plurality of antennas configured to receive wireless communications signals through the large bandwidth communication. The receiver also includes a number of radio frequency (RF) chains, each including a low-bit analog to digital converter (ADC) configured to preform precoding to receive the data and control signals. The receiver further includes a baseband processor configured to perform baseband detection.
