-* @brief Initialization function for the Q15 LMS filter.
-* @param[in] *S points to an instance of the Q15 LMS filter structure.
-* @param[in] numTaps number of filter coefficients.
-* @param[in] *pCoeffs points to the coefficient buffer.
-* @param[in] *pState points to the state buffer.
-* @param[in] mu step size that controls filter coefficient updates.
-* @param[in] blockSize number of samples to process.
-* @param[in] postShift bit shift applied to coefficients.
-* @return none.
-*
-* \par Description:
-* <code>pCoeffs</code> points to the array of filter coefficients stored in time reversed order:
-* <pre>
-* {b[numTaps-1], b[numTaps-2], b[N-2], ..., b[1], b[0]}
-* </pre>
-* The initial filter coefficients serve as a starting point for the adaptive filter.
-* <code>pState</code> points to the array of state variables and size of array is
-* <code>numTaps+blockSize-1</code> samples, where <code>blockSize</code> is the number of
-* input samples processed by each call to <code>arm_lms_q15()</code>.
