Wavelet orthogonal frequency division multiplexing (OFDM) is one of the medium access techniques recommended by the IEEE 1901 working group for broadband communications over electrical networks, and is under consideration for IoT applications. This standard provides a flexible architecture supporting integrated access, smart grid, building, in-home, and mobility platform (vehicle) applications. Wavelet OFDM is a filter bank multicarrier system based on the extended lapped transform, in which the transmitting and receiving filters are obtained from a waveform provided by the standard. In this paper, we explore system performance when other waveforms are employed, studying the trade-off between stopband attenuation and transition band width. Furthermore, an alternative and more efficient way of obtaining the theoretical expressions of the achievable data rate is shown, assuming realistic power line communication noise other than additive white Gaussian noise. To demonstrate the capabilities of wavelet OFDM, the results of simulation of the symbol error rate and the data rate in several systems in platform scenarios (in-vehicle and in-aircraft) are shown.

小波正交频分复用（OFDM）是IEEE 1901工作组推荐的用于通过网络进行宽带通信的媒体访问技术之一，并且正在考虑用于IoT应用。该标准提供了灵活的体系结构，支持集成访问，智能电网，建筑物，家庭和移动平台（车辆）应用程序。小波OFDM是基于扩展重叠变换的滤波器组多载波系统，其中，发送和接收滤波器是从标准提供的波形中获得的。在本文中，我们研究了采用其他波形时的系统性能，研究了阻带衰减和过渡带宽之间的权衡。此外，假定了除加性高斯白噪声之外的实际电力线通信噪声，图中显示了一种获得可达到的数据速率的理论表达式的替代方法，它更加有效。为了演示小波OFDM的功能，显示了在平台场景（车载和飞机）中的几个系统中的符号错误率和数据率的仿真结果。
