Abstract: In the field of technical analysis of modern communication signals, the capability to analyze the characteristics of demodulated signals with unknown coding is of major importance. In this paper, originally developed Communication Bit Stream Analyzer (CBA) software is presented. In addition to various symbol stream/bit stream representations CBA provides a large number of powerful analysis algorithms and bit stream manipulation functions. Functions are categorized by bit manipulation similarity and input/output port type. There are a number of manipulation functions types: bit-to-bit, symbol-to-bit, bit-to-text, bit-to-multimedia and text-to-text. By using these tools, you can obtain technical data from the unknown bit str
