/*		CELP ARRAY SIZE PARAMETERS										 
		MAXNCSIZE		maximum code book size	 (number of codewords)
		MAXL			maximum codeword vector length
		MAXCODE 		maximum code book array length in samples
		MAXLL			maximum LPC analysis frame size
		MAXNO			maximum LPC filter order
		MAXLP			maximum pitch prediction frame size 	 
		MAXNP			maximum pitch prediction order	 
		MMIN			minimum delay pitch predictor (minimum value M)
		MMAX			maximum delay pitch predictor (maximum value M)
		MAXPD			maximum number of pitch delays	 
        MAXPA           maximum pitch analysis buffer length (use to be "idb")
						(assumes code book is updated faster or same as pitch)
		MAXM2			maximum array size for delay parameter
