This a framework to test new ideas in transmission technology. Actual development is a LDPC-coder in

spread
======


Spreading is a simple repetition-code that is used either in a 
multi-user scenario or for simple coding.


despread
--------

This is the despreader, taking the input-signal and doing an
internal convolution.

Inputs:
	SYMBOL_COMPLEX

outputs:
	SYMBOL_COMPLEX

Config:
	factor[MAX_OUTPUTS]<int>: 8
		The factor is the spreading-sequence length

	sequence[MAX_OUTPUTS]<int>: 0x0f
		Each bit is one spreading-symbol. 0 is -1, 1 is 1...


Stats:
	snr<double>:
		The snr of output 0 after despreading


spread
------

This module spreads every input-symbol by a config->factor. It does
this according to the config->sequence, which defines the
spreading-sequence. So, if config->sequence is 0x55, the spreading-
sequence is -1 +1 -1 +1 -1 +1 -1 +1

Inputs:
	SYMBOL_COMPLEX

outputs:
	SYMBOL_COMPLEX

Config:
	factor<int>: 8
		The factor is the spreading-sequence length

	sequence<int>: 0x0f
		Each bit is one spreading-symbol. 0 is -1, 1 is 1...
