—One of the serious challenges, which hamper application of multiple-input multiple-output (MIMO) multicarrier (MC) transmission systems in the cognitive radio (CR) environments, is the synthesis of reliable pilot signals, which can be used for the CR channel sounding. This paper addresses design of the optimal pilot pattern for MIMO-MC CRs. The principal(More)
– This work investigates the performance of linear detector based receivers in MIMO OFDM systems. Two linear detectors are compared that is: Zero Forcing (ZF) and the Minimum Mean Square Error (MMSE). The introduction of interference cancellation will be shown to greatly improve linear detector Bit Error Rates (BER). The performance of one successive(More)
