digital_costas_loop_cc Class Reference
Carrier tracking PLL for QPSKinput: complex; output: complex
The Costas loop can have two output streams: stream 1 is the baseband I and Q; stream 2 is the normalized frequency of the loop.

Detailed Description
Carrier tracking PLL for QPSK
input: complex; output: complex
The Costas loop can have two output streams: stream 1 is the baseband I and Q; stream 2 is the normalized frequency of the loop.
order must be 2, 4, or 8.
