 * added two state variables to enable the use of circular buffers
 * 
 * 5     05-05-20 17:25 Loghman
 * Remove TrainingSeqNo and includ alpha to the ChannelState struct
 * 
 * 4     05-05-19 15:05 Loghman
 * save memory by changing RECIV_TRAIN_SEQ_I_1[ ] toRECIV_TRAIN_SEQ_I_1.
 * 
 * After verification with MATLAB and DSP, this function works well
 * now.
 * 
 * 3     05-05-12 13:40 Loghman
 * Change function from four channel estimation to two channel estimation
 * 
 * 2     05-05-11 18:05 Loghman
 * 
 * 1     05-05-11 17:00 Adrian
 * created and added to VSS
