This paper deals with the capacity behavior of wireless Orthogonal Frequency Division Multiplexing (OFDM)-based spatial multiplexing system when considering realistic channel delay profiles. In both the SISO and the MIMO contexts, we compare the

Freescale关于3GPP LTE PHY层的说明，包括OFDM、MIMO等内容。-This technical white paper provides an overview of the LTE physical layer(PHY), including technologies that are new to cellular such as Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Input M

3GPP LTE关键技术浅析，LTE 改进并增强了空中接口技术，采用 OFDM 及 MIMO 技术作为其无线网络演进的唯一标准。 该文对 OFDM 技术及 MIMO 技术进行了分析，最后提出将OFDM 技术与 MIMO 技术相结合，从而消除由频率选择性衰落带来的影响，达到信息的高速和高可靠性传输。-The key technology of 3GPP LTE, LTE air interface improvements and enhanced technology, the use of O

Application of spread spectrum for satellite land mobile systems is difficult in satellite link because of synchronization and providing code or considerable Doppler shift. This is particularly high for LEO satellites. So that, a Doppler shift carr
