mapper
======


This is a PSK and QAM mapper module which allows both to map and to decide
on the mappings made. It uses hard decisions, but a nice extension would be
to make a module with a soft-output...


slicer
------

 This is a hard-decision slicer that works on two tables, one for
{1,2,3,4}-PSK, the other for {1,2,3,4}-QAM. It can either estimate
the amplitude itself, or it takes the calculated amplitude from a
chest-module.

Inputs:
	SYMBOL_COMPLEX

outputs:
	U8

Config:
	bits_per_symbol<int>: 2
		The bits per symbol

	mafi_id<int>: -1
		The id of the matched filter

	symbol_type<int>: 0
		Which table to take: 0-PSK   1-QAM


mapper
------

A simple mapper-class for demodulator and mapper. 
It supports different PSK and QAM symbols

Inputs:
	U8

outputs:
	SYMBOL_COMPLEX

Config:
	amplitude<int>: 32767
		The amplitude of the symbols

	bits_per_symbol<int>: 2
		The bits per symbol

	symbol_type<int>: 0
		Which table to take: 0-PSK   1-QAM
