This paper discusses the symbol detection complexity of several orthogonal frequency division multiplexing wireless communication schemes using multiple-input multiple-output channels. We investigate spatial diversity (SD) and spatial multiplexing (SM) architectures. For the SD case we discuss an efficient example of space-time block coding, namely the(More)
For increased bandwidth savings in packet networks, speech compression algorithms are applied to reduce the amount of data that needs to be transferred to adequately reconstruct a telephone signal at the receiver. However, such algorithms do not process pure tones (such as dual-tone multi-frequency (DTMF)) with high fidelity, hence such in-band signalling(More)
