    摘要: A transceiver processing hardware (“TPH”) configured to process wireless bit stream(s) includes a minimum mean square error (“MMSE”), an inverse discrete Fourier transform (“IDFT”), a demapper, a descrambler, and a combiner. While MMSE estimates transmit the bit stream, IDFT generates samples associated with the frequency of the bit stream. The demapper, in one embodiment, is configured to discard one or more unused constellation points relating to the frequency of bit stream from the mapping rules. The demapper, in one aspect, includes one or more minimum function components (“MFCs”) and a special treatment component (“STC”). MFCs are able to receive and compare bit stream(s) representing a symbol which corresponds to a quadrature amplitude modulation (“QAM”). STC, in one aspect, is able to force infinity values to the MFCs when the bit stream or stream of bits is identified as ACK or RI with a predefined encoding category.
