- * @brief  Q15 complex conjugate.

- * @param  *pSrc points to the input vector

- * @param  *pDst points to the output vector

- * @param  numSamples number of complex samples in each vector

- * @return none.

- * <b>Scaling and Overflow Behavior:</b>

- * \par

- * The function uses saturating arithmetic.

- * The Q15 value -1 (0x8000) will be saturated to the maximum allowable positive value 0x7FFF.
