In this paper, a simple transmit beamforming scheme over MISO channel in two-way relay networks is proposed. Beam in the proposed scheme is built to maximize sum of the receive power of the two receivers according to their geographic location. The key consideration is to estimate signal direction of arrival (DOA) with the location information supported by localization and tracking instead of using...
In this paper, a new type of collaboration in wireless sensor networks (WSN) is suggested that exploits array processing algorithms to improve the reception of a signal. For receive collaboration, the transmission power during intra-cluster transmissions decreases at the expense of increasing the inter-cluster communications. It is shown that, as a result of using receive collaboration, the destination...
Turbo convolutional codes (TCC) are excellent error correcting codes as they show near Shannon capacity performance in communication systems. However, turbo decoders are computationally complex. Recently, a class of modified turbo codes called low complexity hybrid turbo codes (LCHTC) is proposed with bit error rate (BER) which is almost same as that of turbo codes. In this paper improved low complexity...
Development of a prototype of high power active integrated phased array antenna operating at 5.8 GHz was introduced in this paper. In the AIPAA system for telecommunication as well as wireless power transmission, the two-stage amplifier operated with 27 dBm and insertion loss of the LTCC phase shifter was with 2.6 dB/bit. Under the wireless communication and high power transmission, the BER was measured...
