    • The evolution of high rate data services within future wireless networks will call for new RF access technologies to enable substantial increases in overall system spectral efficiency at an acceptably low cost to the user. Space-Time Coding (STC) is an antenna array processing technology currently simulating considerable Interest across the wireless industry. The invention provides a space-time coding apparatus having an input, a trellis encoder, a modulator, a demultiplexer, and a set of signal outputs wherein the input is operable to receive a stream of data. This allows de-multiplexing to take place after coding and modulation has been performed. The trellis encoder comprises a convolutional encoder operable to sequentially group data to provide coded bits to provide QPSK symbols. By the selection of convolutional encoder rates and/or modulation alphabets STCs of any desired dimensionality may be produced including multi-dimensional codes.
    • 未来无线网络中高速率数据业务的演进将需要新的射频接入技术,以便以可接受的低成本向用户大幅提升整个系统频谱效率。 时空编码(STC)是一种天线阵列处理技术,目前正在模拟无线行业的相当大的兴趣。 本发明提供一种具有输入,网格编码器,调制器,解复用器和一组信号输出的时空编码装置,其中输入可操作以接收数据流。 这允许在进行编码和调制之后进行解复用。 网格编码器包括卷积编码器,其可操作以顺序地分组数据以提供编码比特以提供QPSK符号。 通过选择卷积编码器速率和/或调制字母可以产生任何期望维度的STC,包括多维码。
