An economical tdm design of multichannel Digital Down Converter
Feiteng Luo, Weidong Chen · 2008
Inspired by the idea of hardware time division multiplexing(TDM), a multi-channel Digital Down Converter (DDC) is devised by exploring maximum resource reuse, which is realized by sharing memory, adders and multipliers among several independent channels, so that the resource cost is reduced significantly. Finally, a design example is implemented with FPGA, and simulations verify its feasibility.
