Description: 国外的详细的OFDM设计过程文档,对学习OFDM非常有帮助,并且有仿真结果。-This report discusses the design and implementation of an OFDM modem for a simplex communication
between two PCs over a frequency selective channel. First a brief introduction is
provided by explaining the backrground and the specification of the project. Then the report
deals with the system model. Each block of the OFDM system is described (IFFT/FFT, cyclic
prefix, modulation/demodulation, channel estimation, bit loading). In the following section, the
system architecture is analysed. The transmission protocol, as well as the system parameters
are explained in details. Then, the DSP implementation is discussed. Finally, the results are
provided in the last chapter. Platform: |

Description: we present a new space–time block code for timeand frequency-selective (doubly-selective) channels. It can be interpreted
as the extension of the Alamouti code to doubly-selective channels, and relies on a joint time–frequency reversal of the transmitted sequences. Under
certain channel conditions, the proposed space–time block code belongs
to the class that achieves full spatial, delay, and Doppler diversity using a
maximum-likelihood (ML) receiver, as well as a linear zero-forcing (LZF)
or linear minimum mean-squared error (LMMSE) receiver. For realistic
doubly-selective channels, a real-valued linear data model is presented, for
which different receiver structures can be developed. Platform: |

Description: ns STBC for purely time-selective channels by transforming the
time-selective channels into frequency-selective channels, and by
adjusting existing space–time code designs over frequency-selective
MIMO channels to collect joint space–Doppler gains over purely
time-selective MIMO channels. Further, [14] uses the ideas of [12] to
develop a space–time code that can achieve full space-delay-Doppler
diversity for any number of transmit–receive antennas. However, to
quantify the maximum Doppler diversity order [2], the above papers
rely on a parsimonious critically sampled complex-exponential basis
expansion model (CCE-BEM) for the underlying purely time-selective
or doubly-selective channels [16]. However, the CCE-BEM may have
a large modeling error under certain channel conditions Platform: |
