- Performance of Channel Estimation Assisted Linear Multiuser Receivers for Downlink CDMA Systems With Long Spreading Codes
- With availability of spatial/temporal diversity in the downlink of long code CDMA systems, subspace technique has been shown to be able to estimate channel parameters. Based on the estimated channel, the authors construct three typical linear receivers as ZF, MMSE and RAKE receivers. Due to channel estimation error, those receivers...

- Interpolation-Based Efficient Matrix Inversion for MIMO-OFDM Receivers
- This paper proposes a new class of computationally efficient algorithms for inverting the channel matrices in zero-forcing MIMO-OFDM receivers. Depending on the number of channel taps and the number of antennas, significant complexity reductions can be realized. For the parameter settings used in the IEEE 802.16 standard, savings of up...

- GPS-GSM Mobile Navigator
- With today's stand-alone global position system GPS receivers, you are able to pinpoint your own position. But, what's more useful about stand-alone GPS receivers is that they can transmit your position information to other receivers. Atmel decided to use both of these features to create a wireless vehicle tracking and...

- Cooperation, Competition and Cognition in Wireless Networks
- Nodes and/or clusters of a wireless network operating on the same frequency can operate using three different paradigms: Competition: traditionally, this is information theoretically casted in the framework of interference channels. Cooperation: silent transmitters/receivers can help active transmitters/receivers in the transmission/reception of their messages, but have to extract this message...

- Linear Multiuser Detection for Uplink Long-Code CDMA Systems
- In the uplink of a long-code CDMA system, base station knows spreading codes of all serviced users. Given propagation delays, code-decorrelation can be performed to separate users' inputs in each symbol interval even in a multipath environment. To detect information symbols, first the subspace technique is applied to estimate multipath...
