      • Explain carrier recovery methods for PSK signals. Explain fundamentals of symbol timing recovery
      • Explain minimum distance decoding using calculation of Hamming distance. Illustrate and demonstrate mechanisms of parity check codes, Hamming codes, and cyclic codes. Explain trellis diagrams, illustrate and demonstrate mechanisms of Viterbi algorithm.
      • Calculate coding gain.
        • Explain mechanism of generation and detection of spread spectrum signals. Identify advantages and disadvantages of spread spectrum.
        • Explain mechanism of generation and detection of OFDM signals.
      • Identify advantages and disadvantages of OFDM.
        • Apply software to simulate and analyze digital communications problems
    • Relationship of course to student outcomesThe course supports program outcomes 1, 5, 11 as required by ABET Criterion 3 of EAC (Engineering Accreditation Commission).

      Outcome 1: apply knowledge of mathematics, science, and engineering [ABET Criterion 3 a].

  1. Course Policies

    Each student is expected to attend all of the scheduled classes.

    Student ethics is important (see point no.12). During evaluations (e.g. tests, exams, individual projects, and individual assignments/homework) students must comply with academic and professional honesty. Any breach of integrity will be taken seriously and reported to the appropriate higher authority.


  1. Ethics of a Student as Community Member

    According to the Academic Regulations of ITB, Chapter II Student Ethics at the Institut Teknologi Bandung, First part, Article 3, students of ITB must be able to manifest the spirit of upholding academic and professional honesty and integrity by restraining from dishonest and unfair acts in any form, both inside and outside of the campuses.
