1. A method for wireless communication, comprising:
identifying a coded bit error rate (BER) sensitivity signal-to-noise ratio (SNR) level of a first modulation and coding scheme;
selecting a second modulation and coding scheme based at least in part on the identified coded BER SNR level of the first modulation and coding scheme;
generating a codeword comprising a plurality of symbols, the plurality of symbols including a first group of symbols comprising data symbols with the first modulation and coding scheme and a second group of symbols comprising data modulated pilot symbols with the selected second modulation and coding scheme, wherein the second group of data modulated pilot symbols are used in lieu of pilot symbols; and
transmitting the codeword, wherein transmitting the codeword comprises switching between the first modulation and coding scheme and the selected second modulation and coding scheme for the first group of symbols and the second group of symbols.
