频谱高效、高密度和高速数据传输对于通过物联网（IoT）网络存储和交换敏感信息至关重要。然而，资源受限的物联网设备和有限的现有频谱对下一代技术采用更高效的技术构成了重大挑战。本文提出了一种创新的脉冲索引调制（PIM）架构与随机化技术的模拟脉冲为基础的无分组的大容量数据传输。基于脉冲的压缩简化了短距离无线遥测的编码和解码方案。脉冲随机化技术通过重新排序脉冲位置来创建脉冲盲化，并增加了额外的物理层安全级别。本文描述了PIM的设计、仿真和原型开发，以验证使用标准架构的脉冲数据遥测的可行性和兼容性。仿真结果表明，在3比特系统中，与霍夫曼编码相比，所提出的PIM将数据压缩比提高了2.61倍，处理时间缩短了5.56倍。测试结果表明，在信噪比为10.0 dB时，系统误码率为7.5\，\，\times\，\，10 ^{-4}$，满足数据通信的下限要求，并且通过使用${2 ^{k}}$个脉冲支持${2 ^{k}*k}$比特数据，传输速度提高了k$倍，其中$k$是非负整数。拟议的PIM有可能提高数据速率，增加安全性，以支持下一代物联网网络。
Spectrum-efficient, high-density, and high-speed data transmission are essential to store and exchange sensitive information through Internet of Things (IoT) networks. However, the resource-constrained IoT devices and the limited existing frequency spectrum pose a significant challenge to employing the more efficient technique for the next-generation technology. This article presents an innovative pulse index modulation (PIM) architecture with a randomization technique for analog pulse-based packet-less high-volume data transmission. The pulse-based compression simplifies the encoding and decoding schemes for short-range wireless telemetry. The pulse randomization technique creates the pulse blinding by reordering the pulse positions and adds an extra level of physical-layer security. This article describes the design, simulation, and prototype development of PIM to validate the feasibility and compatibility of pulse-based data telemetry using the standard architecture. Simulation results show that the proposed PIM increases the data compression ratio by 2.61 times and improves the processing time by 5.56 time compared to the Huffman coding for a 3-bit system. Test results show that the BER is $\sim 7.5\,\,\times \,\,10^{-4}$ at 10.0 dB SNR, which satisfies the lower bound for data communication and increases the transmission speed $k$ -times by supporting ${2^{k}*k}$ bits data using ${2^{k}}$ number of pulses, where $k$ is a nonnegative integer number. The proposed PIM has the potential to improve data rate with added security to support the next-generation IoT networks.
