We can now rewrite the received discrete-time signal in the matrix notation as y = α P AVG S ⌣ r h eq + N G h channel + RRC + W h RRC, (6).
Thus, the cyclic mean of the received sequence is given as m ^ y = J R x y = α P AVG [ P r + M ^ e limiter, r ] h eq + M ^ n G h channel + RRC + M ^ w h RRC, (8).
where σ 2 = h RRC 2 σ w 2 + E [ h channel + RRC 2 ] σ n G 2 + E [ h eq 2 ] σ n L 2 models the total interference power based on the Gaussian channel noise, nonlinear power amplifier caused interference and the limiter error.
RRC [35]: The major RRC functions and services include broadcasting system information, establishing/releasing RRC connections, security management, mobility functions, paging, QoS management, and direct messaging between UE and NAS. 4.
Inside this block, the received sequence power is normalized to σ s ̃ ^ 2 = 1 + σ w 2 h RRC 2, which corresponds to the total received power.
The variable σ est 2 corresponds to the total interference power on top of each received pilot symbol and is estimated as σ est 2 = 1 β 2 N c h ^ L S 2 σ n L 2 + ( 1 + 1 / N c ) σ w 2 h RRC 2, (23).
If we use LDDST, we normalize the sequence based on our estimate on the average transmit power σ s ⌣ 2, to be defined in (18), to obtain an estimate for the distorted data sequence, z ̃ ^ = σ s ⌣ ( I - J ) 1 1 - γ 1 + σ w 2 h RRC 2 σ s ̃ ^ 2 s ̃ ^. (10).
It is important to observe that in case of perfect synchronization, Θ=I N, the metric can also be used to evaluate the prototype filter g[n] and the performance of the system, B A. For instance, Figure 10 exhibits the influence of the MF receiver with raised cosine (RC) and root-raised cosine (RRC) [14] as a function of the roll-off parameter α, assuming perfect synchronization.
Based on the LTE-Advanced radio resource control (RRC) specification, A3, A4 and A5 are the three event types defined to trigger the measurement reports.
