Description: DS-CDMA实现基本过程：
<TRANSMITTING END>待传信息--NRZ变换（变成NRZ码）---调制（乘以sqrt(2*eb)*cos(2*w*t)）----扩频（乘以m序列或其他伪随机码）
----信道中传输（有加性噪声）<DURING THE CHANNEL>
---解扩（乘以相同的m序列或其他伪随机码）---解调（乘以sqrt(2*eb)*cos(2*w*t)）----比特判别（sum(i)>0-->1 sum(i)<0--->0）-DS-CDMA to achieve the basic process: <TRANSMITTING END> Information to be passed- NRZ transformation (into NRZ code)--- modulated (multiplied by sqrt (2* eb)* cos (2* w* t ))---- spread spectrum (multiplied by the m-sequence or other pseudo- random code)---- channel transmission (with additive noise) <DURING THE CHANNEL>--- Despreading (multiplied by the same pseudo-random m-sequences or other code)--- demodulation (multiplied by sqrt (2* eb)* cos (2* w* t ))---- bit identification (sum (i)> 0-> 1 sum (i) < 0---> 0) Platform: |

Description: Signal identification represents the task of a receiver
to identify the signal type and its parameters, with applications
to both military and commercial communications. In this paper,
we investigate the identification of spatial multiplexing (SM) and
Alamouti (AL) space-time block code (STBC) with single carrier
frequency division multiple access (SC-FDMA) signals, when
the receiver is equipped with a single antenna. We develop a
discriminating feature based on a fourth-order statistic of the
received signal, as well as a constant false alarm rate decision
criterion which relies on the statistical properties of the feature
estimate. Furthermore, we present the theoretical performance
analysis of the proposed identification algorithm. The algorithm
does not require channel or noise power estimation, modulation
classification, and block synchronization. Simulation results show
the validity of the proposed algorithm, as well as a very good
agreement with the theoretical analysis. Platform: |
