In most communications systems where close carriers can corrupt the signal of interest being received, filter banks typically are needed. Within these systems, the hardware must use filtering, channel ...

This series is excerpted from “Mobile Broadband Multimedia Networks: Techniques, Models and Tools for 4G.” Part two shows how to enhance OFDM with MIMO and other techniques. The many papers noted in ...

In last month’s column I described the principles behind OFDM, how it is generated and received and different parameters that can be adjusted to optimize the transmission for different uses. This ...
