Abstract
An apparatus and method for calculating bit metrics in data receivers. The apparatus of the invention includes a storage unit and a calculator. The storage unit is configured to store a number of modulation-dependent coefficients; it selects as output one of the coefficients in accordance with a modulation mode being used. The calculator receives the selected coefficient from the storage unit and takes a received signal and a channel response in the frequency domain. According to the selected coefficient, the received signal and the channel response, the calculator generates at least N number of bit metrics for an N-bit codeword in the received signal.
