Improving Frequency Acquisition of a Costas Loop

IRE Transactions on Communications Systems, 1977
A Costas loop for tracking a BPSK signal does not acquire when the initial frequency error is comparable to the loop bandwidth. This paper describes methods for deriving control proportional to frequency error so as to improve the frequency acquisition capability by an AFC augmentation.

False Lock Performance of Shuttle Costas Loop Receivers

IEEE Transactions on Communications, 1978
The false (sideband) lock problem in Shuttle Costas loop receivers, in the presencse of noise, is assessed in this paper. False lock margin is defined depending on symbol signal-to-noise ratio rather than in the absence of noise as reported earlier in [4], [5].

Optimum Performance of Suppressed Carrier Receivers with Costas Loop Tracking

IEEE Transactions on Communications, 1977
The performance of suppressed carrier receivers with Costas loop tracking is optimized by proper choice of loop arm filter bandwidth. In particular, it is shown that for a variety of passive arm filter types, there exists, for a given data rate and data signal-signal-to-noise ratio, an optimum filter bandwidth in the sense of minimizing the loop's ...

Modified Costas Loop for BPSK

2017
This chapter describes the modified Costas loop for BPSK. While the conventional Costas loop operated with real signals, the modified circuit works with the so-called pre-envelope signal. This is a complex signal, also referred to as “analytical signal.” The real input signal of this Costas loop is converted to the pre-envelope signal using a Hilbert ...

Introduction: From Phase-Locked Loop to Costas Loop

2017
The Costas loop can be considered an extension of the phase-locked loop (PLL). The PLL, invented 1932 by French engineer Henri de Belleszice, was first used for the synchronous reception of amplitude modulated radio signals with carrier (c). If the modulation index is less than 100%, the modulated signal is always in phase with the carrier signal (c ...

Conventional Costas Loop for QPSK

2017
The operating principle of the conventional Costas loop for QPSK is explained (other types of Costas loops for QPSK are discussed in Chaps. 6 and 9). Dynamic behavior of the loop is described using a novel mathematical model developed by the author. This new model allows the designer of a Costas loop to explicitly compute important key parameters (lock
