摘要： A subcarrier allocation method for use by a transmitter, the transmitter being configured to, when transmitting first and second data streams, allocate pilot symbols for the first and second data streams to subcarriers, such that a first plurality of subcarriers carry the pilot symbols for the first data stream and a second plurality of subcarriers carry the pilot symbols for the second data stream. The method includes allocating, when the transmitter transmits the first data stream but does not transmit the second data stream, the second plurality of subcarriers to carry no formation or information relating to the first data stream.
摘要翻译：一种由发射机使用的副载波分配方法，所述发射机被配置为当发射第一和第二数据流时，将第一和第二数据流的导频符号分配给子载波，使得第一多个子载波携带用于第一数据流和第二多个子载波携带用于第二数据流的导频符号。该方法包括当发射机发送第一数据流但不发送第二数据流时，分配第二多个子载波，以不携带与第一数据流有关的形成或信息。

摘要： A method for pilot design for data to be transmitted by an orthogonal frequency-division multiplexing (OFDM) based communication system, the data being represented by a plurality of OFDM symbols. The method includes allocating pilot symbols for a data stream to be included in ones of the OFDM symbols; and performing a frequency shift on at least one of the OFDM symbols, to reduce frequency distance disparities among the pilot symbols.
摘要翻译：一种用于通过基于正交频分复用（OFDM）的通信系统发送的数据的导频设计的方法，所述数据由多个OFDM符号表示。该方法包括为要被包括在OFDM符号之一中的数据流分配导频符号; 并且对至少一个OFDM符号执行频移，以减少导频符号之间的频率距离差异。

摘要： A module constructs a frame for communication in a communication system that supports a new standard and a legacy standard, the new standard being backward compatible with the legacy standard. The module comprises a first frame generator configured to generate a first portion of the frame, the first portion of the frame to support a first set of data to be transmitted in the legacy standard in each of a number of first bands, a second frame generator configured to generate a second portion of the frame, the second portion of the frame to support a second set of data to be transmitted in the new standard in a second band composed of the first bands, and a frame constructor configured to construct the frame based on the first portion of the frame from the first frame generator and the second portion of the frame from the second frame generator.
摘要翻译：模块在支持新标准和传统标准的通信系统中构建用于通信的帧，新标准与传统标准向后兼容。该模块包括：第一帧发生器，被配置为生成帧的第一部分，帧的第一部分，用于支持在多个第一频带中的每一个中以传统标准传输的第一组数据;第二帧发生器被配置为生成所述帧的第二部分，所述帧的第二部分支持在由所述第一频带组成的第二频带中以新标准发送的第二组数据，以及被构造为基于所述帧的帧构造器在来自第一帧发生器的帧的第一部分和来自第二帧发生器的帧的第二部分。
