In mobile environment, decode quality is largely influenced by multipath fading and Doppler shift. In this paper, we reported improvement of mobile reception for high-definition television (HDTV) of integrated services digital broadcasting - terrestrial (ISDB-T) by using maximum ratio combining (MRC) diversity and using two-dimensional (2D) filter in channel estimation. From computer simulations,...
In this paper, we study the opportunistic cooperative data transmissions based on selective single neighboring cluster head (NCH) relay in clustered wireless sensor networks (WSNs). We propose an opportunistic cooperative data transmission scheme by NCHs and analyze the symbol error rate performance of decode-and-forward (DF) cooperative protocol over Rayleigh fading channels. In our scheme, the source...
For point to point multiple input multiple output systems, Dayal-Brehler-Varanasi have proved that training codes achieve the same diversity order as that of the underlying coherent space time block code (STBC) if a simple minimum mean squared error estimate of the channel formed using the training part is employed for coherent detection of the underlying STBC. In this letter, a similar strategy involving...
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...
A new construction of a full-diversity full-rate space-time block code (FDFR-STBC) is presented in this paper. The design is for 2 transmit antennas and 2 time slots. The code outperforms the previous FDFR-STBC codes in [3], [4], [5], [6] for 1 receive antenna. We reduce the decoding complexity by exploiting the algebraic structure of the code and using the hybrid maximum-likelihood interference cancellation...
