His crimes on the earlier page include being a "nuisance" (May 19), "chewing in class" and "making noise" (separate entries for May 23), "repeated misconduct" (June 13), "silly noises in an examination" (June 15), "sabotage" (June 16), "just no interest whatsoever" (June 20) and "idleness" (June 22).
where H ̄ [ q, n ] represents the channel mean known at the transmitter (estimated channel), Δ[ q,n] denotes the channel estimation noise whose entries are C N ( 0, 1 ), and ρ[ n]∈[0,1] can be a packet-dependent random variable effectively modelling the CSIT accuracy for the current packet, which is also known at the receiver side.
In step 5, we visually inspect the parameter space to identify non-negligible system noise terms (entries of ).
Here, is a noise matrix, whose entries are i.i.d., complex, Gaussian random variables with means zero and variances per dimension.
bounded data symbols of power σ w t 2, and V2 is the M×N2 additive Gaussian noise matrix with entries of zero mean and variance σ v 2.
Also, n is an M × 1 zero-mean noise vector whose entries are of power P n d Finally, n i for i = 1,2,..., K and n are assumed to be statistically independent.
where Hk,i is the Nr×Nt MIMO channel between the serving base station i and user k, and n k denotes the scaled noise vector whose entries are i.i.d.i.d
Each plotted bit error rate (BER) curve is shown as a function of an overall SNR measure, given by SNR = 10 log 10 ∥ Y ∥ F 2 ∥ ℬ ∥ F 2. where ℬ ∈ ℂ F × M r × N × P is the additive noise tensor, whose entries are circularly symmetric complex Gaussian random variables.
For the k th user, the received signal can be denoted as y k [ n ] = H k [ n ] x [ n ] + n k [ n ], (2). in which x[n] ∈ ℂ M ×1 is the BS's transmitted signal, n k [n] is the Gaussian noise vector with entries distributed according to C N ( 0, N 0 W ), where N0 is the noise power density and W is the carrier bandwidth.
