This paper proposes an edge-consistency based frame rate up conversion (FRUC) method for stereoscopic video with limited bandwidth. Firstly, we classify the edge blocks and the flat blocks, respectively, by considering the correlation between the texture image and the depth map. Then, by applying the classification information to motion estimation (ME) and motion vector (MV) post-processing, we obtain...
In this paper, a scrambling scheme based on selected mapping (SLM) without explicit side information for peak-to-average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) employing phase shift keying (PSK) is proposed. Different from phase weighting process employing complex multiplications in SLM, simple scrambling process is implemented in proposed scheme, and the...
Unitary space-time modulation (USTM) is ideally suited for rapid fading scenarios, where neither the transmitter nor the receiver have the channel state information (CSI). However, it has received limited attention compared with the space-time coding schemes that need CSI. An important reason for that is USTM needs too large calculation amount when meeting with a large size constellation. We propose...
Concurrent transmissions can significantly improve the throughput of wireless ad hoc networks. In this paper, a new joint scheduling and transmission power control MAC protocol, termed SPCMAC, is proposed to improve the network throughput and energy efficiency using a single channel and a single transceiver. Scheduling mechanism is adopted to eliminate strong level of interference and enable more...
Space time coding in the case where the channel state information is unknown has received only limited attention, although a signaling scheme called unitary space-time modulation (USTM) has already been proposed. An important reason for the impracticability of USTM is its too large calculation amount when meeting with a large size constellation. We propose a size-reduced method for constellation of...
