	The transmit predistortion circuit applies the following
	function to the output of the raised cosine amplitude shaping:

	f(x) = a4 * x^4 + a3 * x^3 + a2 * x^2 + a1
 
	x is the input from the raised cosine shaping circuit
	(0 ��� x ��� 1), and the output f(x) drives the power amplifier
	(0 means no output power, 1 means maximum output power).
	
	For conventional (non-predistorted output), ��0 = ��2 = ��3 = ��4 = 0 
	and 0 ��� ��1 ��� 1 controls the output power.

	If hard amplitude shaping is selected, 
	both the raised cosine amplitude saper and the predistortion is bypassed, 
	and ��1 used.
