This correspondence examines the number of users that can be supported at a given signal-to-interference ratio in asynchronous direct-sequence code-division multiple-access (DS-CDMA) systems. It is shown that for many chip waveforms the user capacity for asynchronous systems is larger than for optimally designed synchronous systems. The degree to which the(More)
Information transmission through the use of video imagining systems has the potential to build upon the success of imaging communication systems, such as QR Codes and 2D Barcodes. Video communication systems add a temporal dimension to image-based information transmission systems, greatly expanding the amount of data that can be transferred. Such a system(More)
A simple transmit diversity method for asynchronous direct-sequence CDMA systems is proposed. In addition, a receiver structure that can effectively suppress multiple-access interference and exploit transmit diversity is examined. The proposed system is shown to perform well even when there are severe impairments to the desired user from high-power(More)
