Noncoherent MIMO-OFDM Systems — With perfect CSI (Channel State Information) at the receiver and no CSI at the transmitter, and fixed transmit power, capacity increases with bandwidth until it saturates and is given by the receive SNR. In the noncoherent case, where neither the transmitter nor the receiver have CSI, the capacity behavior as a function of bandwidth is markedly different: for full-band OFDM systems (i.e., the transmit signal occupies all time-frequency slots), beyond a certain critical bandwidth, “overspreading” occurs, and the capacity goes to zero. The “overspreading” phenomenon was first described in [10] in the context of SISO systems and can be explained as follows. Increasing the bandwidth results in a proportional increase in the number of independent frequency-diversity branches (provided the channel satisfies the uncorrelated scattering assumption). Since the receiver is not assumed to have CSI, these diversity branches contribute to “channel uncertainty” which leads to a capacity penalty. For large bandwidths (and hence small SNR per degree of freedom) this penalty eventually drives the capacity to zero. In the MIMO case, increasing the number of transmit and receive antennas, on the one hand, increases the total number of degrees of freedom for communication and, on the other hand, results in an increase in channel uncertainty. Since the total available transmit power is split uniformly across transmit antennas, increasing the number of transmit antennas results in a smaller SNR per degree of freedom which leads to the existence of a finite optimum (in the sense of capacity maximizing) number of transmit antennas. Increasing the number of receive antennas, on the other hand, yields an increase in the receive SNR and is hence always beneficial. In summary, for MIMO-OFDM systems operating at bandwidths of several GHz, such as MIMO-based ultra-wideband systems, it is generally not advisable to use a large number of transmit antennas. Figure 2 provides a numerical result illustrating this phenomenon. Page 2 of 11 7/10/2007 http://www.nari.ee.ethz.ch/commth/pubs/files/jsac04.pdf QUESTION: We are in the process developing the following systems: Phase array system, Sectorized antenna system, and Spatial Multiplexing Multiple-In Multiple-Out (MIMO) antenna system. From the FCC’s perspective, what are the calculations for the antenna gain of each system? ANSWER: Basic MIMO types of devices can be simply calculated using the sum of all powers into a single antenna element. This is somewhat of an overestimation in the calculation, but usually should meet mobile applications easily. For portable applications, the antennas are generally much closer together and therefore the overestimation is even smaller. However, the FCC, in its TCB training of May 2005, will accept the following calculations for the aforementioned systems: • Spatial Multiplexing Multiple-In Multiple-Out (MIMO) antenna system: spatial MIMO mode antenna systems in which the power is driven incoherently at each frequency, the directional gain equals the gain of each element. All other modes that drive multiple antennas including legacy modes for communicating with no MIMO devices, the directional gain equals the gain of antenna element plus 10 log the number of antenna elements.

Our client can not understand the question what do you mean, so they can not reply for you. Our client tries to guess what you want to ask and the answer is belowing. Q: Does this device use Spatial Multiplexing Ans: Yes, it supports 2 spatial streams . Q: and does it drive each antenna incoherently? Ans: 1. Does TCB want to know whether there is a phase difference between every antenna ? The phase difference on pcb between every antenna is not a critial parameter in 11n product . I can't find any similar description in 11n standard . If TCB really wants to know it , please explain why he needs this . 2. Does TCB want to know whether the antennas transmit signal at the same time ? Cyclic shift is disable in 11b/g , only Tx 0 is used in 11b/g . Cyclic shift is enable in 11n .
