An Alamouti-type orthogonal space–time-block-code transmission over a relay-based cooperative-diversity system under the influence of the cooperating nodes’ mobility is considered. It is shown that the high nodes' mobility destroys the optimality of the conventional Alamouit's decoder (ALD) employed at the system's destination, which causes severely degraded error performance. A zero-forcing-space–time-decoder...
This paper analyses the performance of a DTT (digital terrestrial television) broadcasting system that includes MIMO-OFDM techniques. The benefits of these techniques are studied comparing the results for different MIMO 2 x 2 (multiple input multiple output), MISO 2 x 1 (multiple input single output) and SISO (single input single output) system configurations. Different propagation channel models...
This paper describes the channelization method for the forward link of ultra mobile broadband (UMB) forward link. It is optimized for encoding/decoding processing time, diversity (especially for latency sensitive data), peak-to-average ratio, link budget (i.e., minimum rate at cell edge), access terminal memory requirements, scalability across various deployment bandwidths to achieve high throughput...
