The physical layer multicast and multithread transmission method is characterized in that a block diagonal precoding matrix of a physical layer multicast wireless scene suitable for a single launching base station and two receiving users is iterated and constructed through a combined triangularization ...
Simulation results show that under a channel-coded, many-user setting, the proposed multicast transceiver schemes yield significant SNR gains over SDR-based beamforming at the same bit error rate level.[ABSTRACT FROM PUBLISHER] 展开 关键词: Multicast capacity physical-layer multicasting semidefinite ...
1、物理层物理层(physicallayer)涉及到通信在信道上传输的原始比特流。设计上必须保证一方发出二进制“1”时,另一方收到的也是“1”而不是“0”。这里的典型问题是:(1)用多少伏电压表示“1”,多少伏电压表示“0”;(2)一个比特持续多少微秒;(3)传输是否在两个方向上同时进行;(4)最初的连接如何...
The inherent multicast nature of the wireless medium can be exploited over two hop networks paves a way for Physical layer multicasting. The system performance gain can be achieved through multicast diversity achieved with dualamplify-and-forward (AF) Relay schemes. The dual AF relaymulticast scheme...
modulation/demodulation, coding/decoding, and MIMO techniques. The Physical Layer uses different channels: Physical Down Link Shared Channel (PDL-SCH), Physical Broadcast Channel (PBCH), Physical Multicast Channel (PMCH), Physical Uplink Shared Channel (PUSCH) and Physical Random Access Channel (PRAC...
This channel defines the physical layer structure to carry Multimedia Broadcast and Multicast Services (MBMS). This control channel occupy the first 1, 2, or 3 OFDM symbols in a subframe extending over the entire system bandwidth. For PMCH channel QPSK, 16QAM, 64QAM modulations are used. ...
