  • Evaluating the average probability of symbol error for different bandpass modulation schemes Comparing different modulation schemes based on their error performances. Channel coding: Transforming signals to improve communications performance by increasing the robustness against channel impairments (noise, interference, fading, ..) Waveform coding: Transforming waveforms to better waveforms Structured sequences: Transforming data sequences into better sequences, having structured redundancy. “Better” in the sense of making the decision process less subject to errors....

  • • Tín hiệu truyền qua kênh truyền sẽ bị ảnh hưởng bởi nhiễu, can nhiễu, fading… là tín hiệu đầu thu bị sai. • Mã hóa kênh: dùng để bảo vệ dữ liệu không bị sai bằng cách thêm vào các bit dư thừa (redundancy). • Ý tưởng mã hóa kênh là gởi một chuỗi bit có khả năng sửa lỗi • Mã hóa kênh không làm giảm lỗi bit truyền mà chỉ làm giảm lỗi bit dữ liệu (bảng tin) • Có hai loại mã hóa kênh cơ bản là: Block codes và Convolutional codes...

  • Another class of linear codes, known as Convolutional codes. We study the structure of the encoder. We study different ways for representing the encoder.Convolutional codes offer an approach to error control coding substantially different from that of block codes. A convolutional encoder: encodes the entire data stream, into a single codeword. does not need to segment the data stream into blocks of fixed size (Convolutional codes are often forced to block structure by periodic truncation). is a machine with memory.
