Diversity and multiplexing: a fundamental tradeoff in multiple-antenna channels

To perm this analysis, we can assume, without loss of generality, that This is because hence, swapping has no effect on the mutual inmation, except a scaling factor of on the SNR, which can be ignored on the scale of interest We start with the following example Example Single-Antenna Channel : Consider the single-antenna fading channel 8 9 where is Rayleigh distributed, To achieve a spatial multiplexing gain of, we set the input data.

Let be the nonzero eigenvalues of, define the rom variables Since the error probability depends on the channel matrix only through s, we can rewrite the bad-channel event in the space of as Equation 26 thus becomes error MIMO: What shall we do with all these degrees of freedom?

Сьюзан и так его поняла. Пока файл Цифровой крепости не подменен модифицированной версией, копия ключа, находившаяся у Танкадо, продолжает представлять собой огромную опасность. - Когда мы внесем эту поправку, - добавил Стратмор, - мне будет все равно, сколько ключей гуляет по свету: чем их больше, тем забавнее.  - Он жестом попросил ее возобновить поиск.  - Но пока этого не произошло, мы в цейтноте. Сьюзан открыла рот, желая сказать, что она все понимает, но ее слова были заглушены внезапным пронзительным звуком.

Я же его личный помощник. - Дай мне. Бринкерхофф не верил своим ушам. - Мидж, я ни под каким видом не пущу тебя в кабинет директора. - Ты должен это сделать! - потребовала она и, отвернувшись, начала что-то печатать на клавиатуре Большого Брата.  - Мне нужен список очередности работы на ТРАНСТЕКСТЕ.

Вниз. Скорее. Еще одна спираль. Ему все время казалось, что Беккер совсем рядом, за углом. Одним глазом он следил за тенью, другим - за ступенями под ногами. Вдруг Халохоту показалось, что тень Беккера как бы споткнулась.

Хейл лично знаком с Танкадо. И снова постаралась держаться с подчеркнутым безразличием. - Он поздравил меня с обнаружением черного хода в Попрыгунчике, - продолжал Хейл.

Вы должны найти это кольцо. Беккер глубоко вздохнул и перестал жаловаться на судьбу. Ему хотелось домой. Он посмотрел на дверь с номером 301.

 - Что… Но было уже поздно. Дэвид положил трубку. Она долго лежала без сна, ожидая его звонка. Но телефон молчал. В подавленном настроении Сьюзан приняла ванну.

 Ты по-прежнему хочешь уйти. Сьюзан посмотрела на. Сидя рядом с великим Тревором Стратмором, она невольно почувствовала, что страхи ее покинули.
