[File Format] WirelesscoherentOFDMmodemsimulation DL : 0: This project aim was to build wireless software modem for data communication between two computers using an acoustic interface in the voice frequency range (20Hz– 20,000Hz). The transmitting antenna is a speaker (frequency response of: 90Hz – 20,000Hz) and the receiving antenna is a microphone (frequency response of: 100Hz – 16,000Hz). The test files used as information files were text files. This goal was attained both in an incoherent scheme and in a coherent scheme. Build under Matlab code, our modem uses OFDM (orthogonal frequency division multiplexing) modulation, synchronization by LMS sequence, channel estimation (no equalizer) via pilot tones. The symbols are either PSK or ASK for a constellation size of 2 or 4. To optimize the probability of error, these symbols were mapped using Gray mapping.

[Printing program] final_report DL : 0: 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.
