In this paper, the reconstruction of the feedback polynomial as well as the initial state of a linear feedback shift register (LFSR) in a synchronous scrambler placed after a channel encoder is studied. The study is first based on the assumption that the channel is noiseless and then extended to the noisy channel condition. The dual words, which are orthogonal to the codewords generated by the channel encoder, are used in the reconstruction algorithm. The number of bits required by the new algorithm is compared with another recently proposed algorithm and results show that the number of bits required to do the reconstruction can be significantly reduced.

“…Unlike usual wireless communication systems, where the components and parameters of the transmitter are all known by the receiver, in reverse engineering [1–8], the majority of them will not be known. For example, blind identification has a spread application in software defined radio [9–11], non‐cooperative communication [12–18] etc. Reverse engineering is a new field of research in both communication technology and information theory.…”

“…During the past few years, software defined radio [1] with radio features that can be freely changed by software has been developed [2][3][4][5][6]. By creating software for executing radio functions that had conventionally been implemented by hardware, software defined radio enables various communication systems to be supported or new functions to be added through programming, making wireless terminals more flexible.…”

In recent years, software defined radio has attracted attention as radio with features that can be freely changed by software. The authors have previously proposed a concept for a receiver that converts the entire bandwidth of a desired system to digital signals and selects the signals of the desired channel in the digital stage. In addition, they have applied this concept to propose a basic configuration of a software defined radio using the direct conversion and low intermediate frequency (low‐IF) principle. In this paper, the authors investigated a specific implementation of the previously proposed wideband analog stage using the direct conversion and low‐IF principle and digital stage having an image rejection function and evaluated this implementation through experiments using the 1.5‐ and 1.9‐GHz bands. The results showed that a 10‐MHz wideband was implemented for the bandwidth and that at least 25 dB was obtained for the image rejection ratio by using the direct conversion principle and at least 61 dB was obtained by using the low‐IF principle. In addition, the authors performed the evaluation using the entire receiver and confirmed that the implementation was error free for multiple modulation modes. © 2003 Wiley Periodicals, Inc.
