ConvEncode: Convolutional encoding of a message.

In DaniWi/Channelcoding: channelcoding

Description

Produces a convolutional code of a message.

Usage

ConvEncode(message, conv.encoder = NULL, terminate = TRUE,
  punctuation.matrix = NULL, visualize = FALSE)

Arguments

message	The message to be encoded.
conv.encoder	Convolutional encoder used for encoding.
terminate	Flag if the code should be terminated.
punctuation.matrix	If not null the encoded message is punctured with the punctuation matrix.
visualize	If TRUE a beamer PDF file is generated showing the encode process.

Value

The encoded message with signal values -1,+1 which map to 1,0 respectively.

Examples

coder <- ConvGenerateEncoder(2,2,c(7,5))
plain <- c(1,0,0,1,1)

# standard encoding with termination
ConvEncode(plain, coder)

# without termination
ConvEncode(plain, coder, terminate = FALSE)

# with punctuation and visualization
# punctuation <- ConvGetPunctuationMatrix(c(1,1,0,1,1,0), coder)
# ConvEncode(plain, coder, punctuation.matrix = punctuation, visualize = TRUE)

# use default values
ConvEncode(plain)
