We investigate the case of independent Rayleigh faded paths between antenna elements and find that with high probability extraordinary capacity is available. Compared to the baseline n = 1 case, which by Shannon’s classical formula scales as one more bit/cycle for every 3 dB of signaltonoise ratio (SNR) increase, remarkably withMEAs, the scaling is almost like n more bits/cycle for each 3 dB increase in SNR. To illustrate how great this capacity is, even for small n, take the cases n = 2, 4 and 16 at an average received SNR of 21 dB. For over 99 of the channels the capacity is about 7, 19 and 88 bits/cycle respectively, while if n = 1 there is only about 1.2 bit/cycle at the 99 level. For say a symbol rate equal to the channel bandwith, since it is the bits/symbol/dimension that is relevant for signal constellations, these higher capacities are not unreasonable. The 19 bits/cycle for n = 4 amounts to 4.75 bits/symbol/dimension while 88 bits/cycle for n = 16 amounts t

0. Install the rp-pppoe-software -------------------------------- You should have already done this by the time you re reading this. If not, go back and read README. 1. Set up your Ethernet hardware -------------------------------- First, make sure the Ethernet card you intend to use with the modem is visible to the Linux kernel. Just how to do this is beyond the scope of this document. However, if the card is the only Ethernet card in the system, executing: ifconfig eth0 should display something like this: eth0 Link encap:Ethernet HWaddr 00:60:67:62:31:D4 plust some more lines. Your HWaddr will be different. As long as you see the HWaddr line, your card should be working. DO NOT assign an IP address to the Ethernet card. DO NOT configure the card to come up at boot time.-0.
