Analysis and construction of full-diversity joint network-LDPC codes for cooperative communications

Cooperative communication is a well known technique to yield transmit diversity and network coding can increase the spectral efficiency. These two techniques can be combined to achieve a double diversity order for a maximum coding rate Rc = 2/3 on …

Application layer ARQ for protecting video packets over an indoor MIMO-OFDM link with correlated block fading

The quality of experience (QoE) of IP-packetized streaming video is affected by both packet loss and packet delay variations. When the network delivering the video content contains a wireless link, occasional deep fades give rise to bursts of packet …

BER analysis of square OSTBCs with LMMSE channel estimation in arbitrarily correlated Rayleigh fading channels

In this paper, we examine the bit error rate (BER) performance of square orthogonal space-time block codes (OSTBCs) under arbitrarily correlated Rayleigh fading channels. We consider a mismatched maximum-likelihood receiver that obtains the channel …

Wireless communication for firefighters using dual-polarized textile antennas integrated in their garment

A compact wearable antenna system, completely made out of textile materials for integration into protective garments, is proposed. The system implements combined pattern and polarization diversity to improve the quality of the communication link. The …

Exact BER analysis for orthogonal space-time block codes on arbitrary fading channels with imperfect channel estimation

In this contribution, we provide an exact bit error rate (BER) analysis of orthogonal space-time block codes over arbitrarily distributed (possibly correlated) block fading channels with imperfect channel estimation. The transmitted symbols belong to …

Exact BER analysis for square orthogonal space-time block codes on arbitrary fading channels with imperfect channel estimation

In this contribution, we examine the effect of imperfect channel estimation on the bit error rate (BER) performance of square orthogonal space-time block codes (OSTBCs). The propagation channels from the N-t transmit antennas to each of the N-r …
