Thày giáo bắt bọn em dịch tài liệu về WiMax (802.16e) làm bt lớn, nhưng có nhiều từ chuyên nghành (từ màu đỏ í) khó quá hok dịch nổi nên em cầu cứu các anh chị, mong được giải đáp càng sớm càng tốt. Em cảm ơn nhiều !!
802.16e provides specifications for non line of sight, mobile wireless communications in the frequency range of 2-6 GHz. It is well implemented by using OFDMA as its physical layer scheme.
Detecting the timing offset of a new mobile user, entering the network, which is not time aligned using cross-correlation and ‘auto-correlation’ in time domain and cross-correlation in frequency domain at the base station has been simulated.
The use of adaptive antenna system in 802.16e improves the system performance, where beamforming is implemented in the direction of desired user.
