Enum ConvCode 

pub enum ConvCode {
    K5,
    DvbK7,
}

Selects the convolutional mother code. Both are rate-1/2, zero-tail terminated, and share the puncture matrices in PunctureRate.

Variants

K5

The crate’s original constraint-length-5 code, G0 = 0o25, G1 = 0o23. Also the code PSK31 uses (codec::conv_encode). Default for backward compatibility.

DvbK7

DVB-T’s constraint-length-7 code, G0 = 0o171, G1 = 0o133 (ETSI EN 300 744 §4.3.3). The conformant DVB-T inner code.

Implementations

impl ConvCode

pub const fn constraint_length(self) -> usize

Constraint length K (register width is K − 1).

pub const fn reg_bits(self) -> usize

Register width in bits, K − 1 (also the number of zero tail bits).

pub const fn num_states(self) -> usize

Number of trellis states, 2^(K−1).

pub const fn tail_bits(self) -> usize

Number of zero tail bits appended to terminate the trellis, K − 1.
