The data rate are in units of bits per OFDM symbol, or equivalently bits per second per Hertz (bps/Hz).
The spectral-efficiency is expressed in terms of bits per second per hertz per user bits/s/Hz/User).
The optimal value of under partial interference is, and the capacity across unit cut is bits per second per kilometer.
Therefore, for, the maximum capacity across unit cut under the physical model is bits per second per kilometer.
The MIMO channel capacity expressed in bits per second per hertz (bit/s/Hz) is given by[1, 2] C = log 2 det I n R + SNR n T H F H F † = log 2 det I n T + SNR n T H F † H F, (6).
For multicell networks, EE requires new approaches for interference management as compared to the more traditional performance metrics [12 17], which mainly aim at maximizing the spectral efficiency (SE) in terms of bits per second per hertz.
Without loss of generality, we simply assume that video layer n is transmitted in AMC mode n with the spectral efficiency of R n (bits per second per hertz).
Accounting for all the overheads due to guard interval, channel coding, pilot, and null subcarriers, the overall spectral efficiency in terms of bits per second per Hz (bits/s/Hz) is (4).
This new cellular communication system, built upon a redesigned physical layer and based on an orthogonal frequency division multiple access (OFDMA) modulation, features robust performance in challenging multipath environments and substantially improves the performance of the wireless channel in terms of bits per second per Hertz (bps/Hz).
If we denote the effective capacity normalized by bandwidth or equivalently the spectral efficiency in bits per second per Hertz by C E SNR, θ = C E SNR, θ B = - 1 θ T B log e E e - θ T R i, (8).
