Data-modulated pilots for phase and gain detectors

An apparatus to mitigate an unwanted increase in a coding rate of a wireless communication signal, comprising:

• means for receiving a plurality of symbols comprising a transmitted codeword, the plurality of symbols including a first group of data symbols with a first modulation and coding scheme and a second group of data modulated pilot symbols with a second modulation and coding scheme, wherein the second group of data modulated pilot symbols are used in lieu of pilot symbols;
• and
• means for adaptively switching between applicable demodulation schemes for each group of the plurality of symbols.

A computer program product for mitigating an unwanted increase in a coding rate of a wireless communication signal, the computer program product comprising a non-transitory computer-readable medium storing instructions executable by a processor to:

• receive a plurality of symbols comprising a transmitted codeword, the plurality of symbols including a first group of data symbols with a first modulation and coding scheme and a second group of data modulated pilot symbols with a second modulation and coding scheme, wherein the second group of data modulated pilot symbols are used in lieu of pilot symbols;
• and
• adaptively switch between applicable demodulation schemes for each group of the plurality of symbols.
