The Disk SAMPLE is used with Classpnp.sys as disk driver. The SAMPLE supports Plug and Play, Power Management, WMI, and failure prediction (S.M.A.R.T.), and it is 64-bit compliant.
The sfloppy SAMPLE is a super floppy driver that resides in the directory \\Ntddk\Src\Storage\sfloppy. It is a class driver for Super Floppy disk drives. It sits a level above the port driver (ATAPI, USB, etc) in the driver stack, and brokers communication between the application level and the port driver. The floppy driver takes requests from filesystem drivers and then sends the appropriate SCSI_REQUEST_BLOCK (SRB) to the port driver. It is compatible with x86 and IA64 platforms.
This paper examines the asymptotic (large SAMPLE) performance
of a family of non-data aided feedforward (NDA FF) nonlinear
least-squares (NLS) type carrier frequency estimators for burst-mode
phase shift keying (PSK) modulations transmitted through AWGN and
flat Ricean-fading channels. The asymptotic performance of these estimators
is established in closed-form expression and compared with the
modified Cram`er-Rao bound (MCRB). A best linear unbiased estimator
(BLUE), which exhibits the lowest asymptotic variance within the family
of NDA FF NLS-type estimators, is also proposed.
