8psk verilog

8PSK (8-Phase Shift Keying) is a modulation scheme commonly used in digital communication systems. If you are looking for Verilog code to implement 8PSK modulation and demodulation, I can provide you with a basic example.

Here is a simple Verilog code snippet for 8PSK modulation:

module PSK_8_mod(
  input wire [2:0] data_in,
  output wire [1:0] mod_out
);

  always @*
    case(data_in)
      3'b000: mod_out = 2'b00;
      3'b001: mod_out = 2'b01;
      3'b010: mod_out = 2'b11;
      3'b011: mod_out = 2'b10;
      3'b100: mod_out = 2'b01;
      3'b101: mod_out = 2'b10;
      3'b110: mod_out = 2'b00;
      3'b111: mod_out = 2'b11;
      default: mod_out = 2'b00; // Handle invalid input
    endcase

endmodule

This module takes a 3-bit input `data_in` and outputs the corresponding 2-bit modulation signal `mod_out`. The input values represent the symbols in the 8PSK constellation.

For the demodulation of the received signals, you would typically need additional components such as phase detectors or matched filters. The exact implementation details would depend on your specific system requirements.

Keep in mind that this is just a basic example, and there may be more complex techniques or optimizations depending on your specific application.
