20100329378 | MULTIPLE ANTENNA SPATIAL MULTIPLEXING OPTIMAL DETECTION - MIMO detection is described that reduces the complexity of computations for finding the soft bit output. The detection process includes QR factorization splitting the distance calculations into two groups, subset lookup using a last cross constellation set (LCCS) lookup, and minimal distance lookup with soft bit output calculation. By grouping the distance calculations into a first group that has one antenna transmitting using a modulation scheme with a generally square constellation diagram and a second group for all of the other antenna constellation diagrams, the LCCS lookup process may be used which substantially reduces the number of calculations to be made in the detection process. Moreover, in the special case of 2×2 antenna, QR factorization is performed by applying a scaled Givens rotation to the channel matrix. The application of the scaled Givens rotation operator eliminates any square root operations that would be performed in a standard QR factorization. | 12-30-2010 |

20150243275 | VOICE FONT SPEAKER AND PROSODY INTERPOLATION - Multi-voice font interpolation is provided. A multi-voice font interpolation engine allows the production of computer generated speech with a wide variety of speaker characteristics and/or prosody by interpolating speaker characteristics and prosody from existing fonts. Using prediction models from multiple voice fonts, the multi-voice font interpolation engine predicts values for the parameters that influence speaker characteristics and/or prosody for the phoneme sequence obtained from the text to spoken. For each parameter, additional parameter values are generated by a weighted interpolation from the predicted values. Modifying an existing voice font with the interpolated parameters changes the style and/or emotion of the speech while retaining the base sound qualities of the original voice. The multi-voice font interpolation engine allows the speaker characteristics and/or prosody to be transplanted from one voice font to another or entirely new speaker characteristics and/or prosody to be generated for an existing voice font. | 08-27-2015 |
