$Log: /MIMO/Receiver/rxmain.h $ 
 * 
 * 9     05-06-01 0:48 Adrian
 * WORKBUFFLEN needs to be 2*BUFFSIZE and also increased the symbolbuffer
 * size but is not essential
 * 
 * 8     05-05-27 20:42 Adrian
 * changed SYMBOLBUFLEN since this is now implemented as a circular
 * buffer, and added eRX_RECSYNC to typRX_eRxState
 * 
 * 7     05-05-26 19:17 Adrian
 * increased the file buffer size to 8 MB
 * 
 * 6     05-05-22 19:11 Adrian
 * added eRX_TERMINATION to typRX_eRxState (according to rxhostcomm.c) and
 * uiStartIndex to typRX_RECEIVESTATE
 * 
 * 5     20.05.05 8:58 Adrian
 * extended typRX_RECEIVESTATE with RxMethod, uFileSize, uNoOfBlocks and
 * iSyncStarted
 * 
 * 4     05-05-19 12:27 Adrian
 * modifyed the two receiver states
 * 
 * 3     05-05-17 19:26 Adrian
 * modified typRX_eRxState and typRX_eRcvState
 * 
 * 2     05-05-16 17:06 Adrian
 * Moved the states and structures typRX_eRxState, typRX_eRcvState, and
 * typRX_RECEIVESTATE from commondef.h to here.
 * 
 * 1     05-05-11 17:00 Adrian
 * created and added to VSS
