A method and apparatus for signal acquisition with transmit blanking compensation compensates for collisions between a desired received signal and a transmitted signal. A blanking block blanks a received signal when the transmitted signal is transmitted and stops blanking when the transmitted signal stops to provide a received signal with blanking. A correlation block correlates the received signal with blanking with a known sequence of symbols corresponding to the desired received signal and outputs a correlation metric and a number of symbols blanked. Means for adjusting the correlation metric or a variable threshold using the number of symbols blanked are provided. A decision block compares the adjusted correlation metric to a fixed threshold or the correlation metric to the variable threshold. If the adjusted correlation metric exceeds the threshold or if the correlation metric exceeds the variable threshold, the decision block determines that the desired signal is detected.
