近年來車子內部的電子控制單位(ECU, electronic control unit)逐漸增加，而這
些控制單位間的資料傳遞都需要額外的特定拉線。車用電力線通訊的概念即是利
用車子內部電力線做為資料傳輸的媒介，進而降低特定拉線所需的花費或者是對
汽車所造成的重量。
在本篇論文中，基於相關文獻的研究與探討，提出了更為符合汽車內部真實
情況的車用電力線通道模型，並針對該通道模型設計出一個適用於車用電力線通
訊的基頻收發機。整個收發機的設計是依照標準設計流程，從相關文獻的研讀、
系統規格的設計、功能性的模擬和系統演算法的決定，到整個系統的邏輯電路設
計。
在發送機的部分，針對同步設計了相對應的訓練序列(preamble)；在接收機
的部分則包含:降低車用電力線通道中的衝擊性噪音(impulsive noise)效果的非線
性消隱工藝(nonlinear blanking process)、封包偵測(packet detection)、時間同步
(timing synchronization)、採樣頻率偏移追蹤(sampling clock offset tracking loop)、
通道估計/等化(channel estimation/equalization)和快速傅立葉轉換(FFT)。整個系統
在多路徑汽車電力線的環境下，錯誤率可以達到10^-3 而訊雜比為65 dB。
在邏輯電路設計上，是以低複雜度為主要的考量。電路是採用暫存器交換層
級語言(RTL)描述並作驗證 ，再利用tsmc 0.18 微米1p6m 的技術來合成邏輯電
路。經由NAND 閘的面積估計，所設計電路約有513k 的gate count 大小。

In-vehicle power line communications (PLC) provide a solution for high data communications
in the automotive networks without increasing volume, weight and cost of the wiring
harnesses. This thesis presents the vehicle power line channel model, which contains multipath
fading, impulsive noise, background white noise, and sampling clock offset (SCO) impairments.
Also, we propose the design of baseband inner transceiver, which is specifically
aimed at the built channel model. The proposed design employs the bandwidth (BW) from
1:8 to 50 MHz and supports BPSK-QAM1024 modulation scheme with maximum data rate
212:83 Mbps. In the transmitter part, the corresponding preamble structure is designed. In
the receiver part, it contains packet detection, symbol timing synchronization, sampling clock
offset synchronization, channel estimation/equalization, and the nonlinear blanking process
for reducing the power of impulsive noise. Functional simulations show the validity of these
algorithms and system performance of the proposed transceiver. Under the impulsive noise
scenario, the simulation result shows the requirement of SINR (Signal to Interference and
Noise Ratio) 72 dB for bit error rate (BER) of 10−3. The ability of impulsive noise resistance,
which is provided by the simple non-linear blanking process and large FFT size, under low
SINR ( < 64 dB) condition is also shown in the simulation result. The comparison with other
works is also obtained.
The architecture and logic design of proposed receiver are also presented. To simplified
the critical component of whole receiver, a radix-2/4/8/16 single-path delay feedback (SDF)
fast fourier transform (FFT) architecture is adopted. It requires only two complex multipliers,
and all the trivial multiplications are further simplified by shifting and addition. The cubic
interpolator is implemented by Farrow structure to reduce the cost of multiplier. The other
components, such as delay correlator, SCO estimator, loop filter, cubic controller and division free hard-demapper, are also designed and presented. Eventually, the functionality of
proposed logic design are verified by the test and golden patterns generated form fix-pointed
Matlab model NC-Verilog RTL simulation.
