摘要： A multiple-input multiple-output code division multiple access (MIMO-CDMA) wireless communication equipment has a transmitter and a receiver. The transmitter has an encoder for receiving and encoding a plurality of data, and sending the data to a quadrature phase-shift keying (QPSK) unit. The QPSK unit conducts QPSK modulating to an output of the encoder and sends it to a space-time block coding (STBC) unit or a space multiplexer to process space-time coding or space coding. A plurality of data frame generating modules generate a data frame respectively based on the output of the STBC unit, a plurality of preamble codes generated by a preamble code spreading unit, a pilot code and a cyclic prefix. The data frame is sent to the receiver via a plurality of transmitting antennas.

摘要： The present invention relates to a transmission system with interference avoidance capability, which includes a transmission apparatus and a receiving apparatus. The transmission method thereof receives first data by means of an interference-processing module of the transmission apparatus and adds a plurality of extension data to the first data to produce second data for replacing a plurality of data corresponding to an interfered band in the second data with zero data, and then producing transmission data. The transmission data is converted to a radio-frequency signal by a transmission-processing module and transmitted to the receiving apparatus. Thereby, signal interference can be prevented by avoiding spectrum overlap regions.

摘要： A pre-verifying method for software/hardware design of a communication system includes simulating a process of sending a data frame from a transmitter to a receiver with a transceiver algorithm meeting a preset specification for obtaining simulation parameters. A transmitter hardware platform sends the data frame via an antenna. A receiver hardware platform receives an echo signal of the data frame and compares each parameter of the echo signal with the simulation parameters. The comparison result of various parameters of the echo signal and the simulation parameters is verified to be in a desired range or not. When the comparison result is not in the desired range, the transceiver algorithm is adjusted. When the comparison result is in the desired range, the transceiver algorithm is converted to a hardware program language format to be written in a programmable module to perform the action of the transmitter and the receiver.
