Systems and methodologies are described that facilitate monitoring transmitter performance in a wireless communication environment. A metric or metrics associated with one or more pilot symbols can be generated and used to evaluate performance. To generate pilot metrics, a signal analyzer can be used to sample the output of a transmitter and the sampled signal can be propagated to a processor. The processor can generate frequency domain channel estimates for subcarriers. Average channel estimates for the subcarriers can be used with the known pilot symbols to determine noise or error for each subcarrier, which can be used to generate the noise variance for each of the pilot symbols. A pilot modulation error metric can be generated based upon the average channel estimates and noise variance.
