Syllabus

Prerequisites

6.011 and 6.111

Topics

The course will focus on four major categories as outlined below:

  1. Introduction to digital communications
    • Modulation and detection, vector channel representation
    • Equalization
    • Multi-channel systems (modulation methods, waterfiling, bit loading)
    • Practical examples including 802.11a
    • Coding – sequence detection, gap, convolutional and block codes

  2. ASIC design fundamentals
    • ASIC design flow, tools, system-on-a-chip design issues
    • Micro-architectures and transformations (parallelism, pipelining, folding, time-multiplexing)
    • Hardware description languages: introduction to Bluespec™ and Verilog® review

  3. Theory and building blocks
    • Fast fourier transform (theory, fast algorithms and VLSI implementations)
    • Convolutional and Trellis codes, and Viterbi algorithm (theory, algorithms and VLSI implementations)
    • Synchronization (phase and frequency tracking loops, algorithms and VLSI implementations)
    • Block codes (Hamming, BCH, Reed-Solomon), basic theory and VLSI implementations

  4. Wireless channel fundamentals
    • Properties and modeling (fading, Doppler effect,...)
    • Channel estimation (theory and VLSI implementations)
