Inheritance diagram for DQPSKModulator

class kaira.modulations.DQPSKModulator(*args: Any, **kwargs: Any)

Bases: DPSKModulator

Differential Quadrature Phase-Shift Keying (DQPSK) modulator.

Methods

__init__	Initialize DQPSK Modulator.
forward	Modulate bit groups to DPSK symbols.
plot_constellation	Plot the DPSK constellation diagram.
reset_state	Reset the internal phase memory to the default state.

Attributes

bits_per_symbol	Number of bits per symbol.
constellation
bit_patterns

property bits_per_symbol: int

Number of bits per symbol.

forward(x: Tensor, *args, **kwargs) → Tensor

Modulate bit groups to DPSK symbols.

Parameters:

• x – Input tensor of bits with shape (…, K*N), where K is bits_per_symbol, or direct symbol indices with shape (…, N) where each value is < order

• *args – Variable length argument list.

• **kwargs – Arbitrary keyword arguments.

Returns:

Complex tensor of DPSK symbols with shape (…, N)

plot_constellation(**kwargs) → Figure

Plot the DPSK constellation diagram.

Parameters:

**kwargs – Additional arguments passed to plot_constellation

Returns:

Matplotlib figure object

reset_state() → None

Reset the internal phase memory to the default state.

constellation: torch.Tensor

bit_patterns: torch.Tensor

__init__(*args: Any, **kwargs: Any)
