Abstract:
1. A method of received signal processing in a wireless communication apparatus comprising: receiving a wireless communication signal; generating initial symbol estimates for data symbols received in a first signal component of the wireless communication signal; forming a statistical representation of symbol magnitudes of the initial symbol estimates; comparing the statistical representation to a number of reference representations to obtain comparison results with respect to each reference representation, wherein each reference representation represents a characteristic symbol magnitude distribution for data symbols that are jointly parameterized according to a particular combination of defined values for two or more signal parameters from among a defined set of signal parameters that includes any two or more of: a symbol modulation format, a received symbol quality, a symbol scaling factor, a symbol impairment variance estimate, and Multiple-Input-Multiple-Output, MIMO, symbol precoding weights; estimating one or more signal parameters for the data symbols, based on evaluating the comparison results; and processing the initial symbol estimates as a function of the estimated one or more signal parameters.
