Member Function Documentation

decode()

void Viterbi_Decoder::decode	(	std::vector< int32_t > &	output_u_int,
		const std::vector< float > &	input_c
	)

Uses the Viterbi algorithm to perform hard-decision decoding of a convolutional code.

Parameters

[out]	output_u_int	Hard decisions on the data bits
[in]	input_c	The received signal in LLR-form. For BPSK, must be in form r = 2*a*y/(sigma^2).

reset()

void Viterbi_Decoder::reset

(

)

Reset internal status.
