RF communication systems that provide combined demodulation and despreading are provided herein. In certain embodiments, an RF communication system generates an in-phase (I) signal and a quadrature-phase (Q) signal based on processing a received spread spectrum signal carrying a sequence of data symbols. The data symbols each have a symbol period and are coded by one or more multi-bit spreading codes. The RF communication system includes a symbol correlator that delays the I signal and the Q signal by an integer number of symbol periods to thereby generate a delayed I signal and a delayed Q signal, respectively. Additionally, the symbol correlator generates a correlation signal based on correlating the delayed I signal to the I signal and correlating the delayed Q signal to the Q signal. The RF communication system processes the correlation signal to recover the sequence of data symbols.
